Product Description

Product Description

Fitness means being active, sleeping well, and eating smarter – and the Fitbit One helps you do all three. During the day, it tracks your steps, distance, calories burned, and stairs climbed. Come nightfall, it measures your sleep cycle to help you see how to sleep better; and it can even wake you in the morning without waking your partner. Your stats upload wirelessly via computer or select mobile devices (like the iPhone 4S). Powered by your stats, you can set goals, and track progress. Stay motivated by earning badges or connecting with friends for support or friendly competitions. Log food, work-outs and more. Bring greater fitness into your life – seamlessly, socially, 24 hours a day.

From the Manufacturer

Keep it Clean: Regularly clean your band and wrist—especially after working out or sweating. Rinse the band with water or wipe it with a small amount of rubbing alcohol. Do NOT use hand soap, body soap, dish soap, hand sanitizers, cleaning wipes or household cleaners which could get trapped beneath the band and irritate skin. Always dry the band well before putting it back on. Keep it Dry: While Fitbit devices are water resistant*, it’s not good for your skin to wear a wet band for long periods of time. If your elastomer band gets wet—like after sweating or showering—rinse and dry it thoroughly before putting it back on your wrist. Be sure your skin is dry before you put your band back on. Don’t Wear It Too Tight: Make sure your band isn’t too tight. Wear the band loosely enough that it can move back and forth on your wrist. If you use Fitbit products with Purepulse Heart Rate tracking, for better heart rate readings during exercise, we suggest wearing the band so it’s secure, but not too tight, and wearing the band higher on your wrist (about 2-3 finger widths above your wrist bone). Lower the band on your wrist and loosen it after exercise. Give Your Wrist a Rest: Prolonged rubbing and pressure may irritate the skin, so give your wrist a break by removing the band for an hour after extended wear.

Important information

Indications

• Make sure your band isn’t too tight. Wear the band loosely enough that it can move back and forth on your wrist. • If you use Fitbit Charge HR , Fitbit Blaze or Fitbit Surge , for better heart rate readings during exercise, we suggest wearing the band so it’s secure, but not too tight, and wearing the band higher on your wrist (about 2-3 finger widths above your wrist bone). Lower the band on your wrist and loosen it after exercise.

Directions

• While Fitbit devices are water resistant*, it’s not good for your skin to wear a wet band for long periods of time. • If your elastomer band gets wet—like after sweating or showering—rinse and dry it thoroughly before putting it back on your wrist. • Be sure your skin is dry before you put your band back on. If Fitbit Blaze gets wet or if you sweat in it, remove and completely dry the band before putting it back on. Give your wrist a rest by taking the band off every now and then, and regularly clean your band and wrist. • Even though Fitbit Flex 2 is swim-proof, it’s important to thoroughly dry your classic elastomer band and tracker, and remove any debris from your device after wear in the water, to avoid skin irritation. Please note that non-elastomer accessories should not be worn in water.

Life-Changing Gadget 2.0 Video Review!
5 Stars
Life-Changing Gadget 2.0 Video Review!
I upgraded from the Ultra. You can read my comprehensive review of the Fitbit Ultra at Fitbit Wireless Activity/Sleep Tracker, Black/Blue.First, I am sold on Fitbit because I've lost over 30 pounds since starting with the Ultra approximately a year ago. I don't work for the company and have received nothing from them for my enthusiasm -- I just find this is something that really works for me.IMPORTANT Before you read further or miss this: You have to have a phone that has Bluetooth capability for this new Fitbit to sync with your phone. If you're upgrading from the Ultra to this Fitbit One for the sync capability, you'll be disappointed if your phone can't sync. If you've got an iPhone, Bluetooth capability is currently only on the iPhone 5 and 4S. You can still upload your data to the computer with a different phone, but the Fitbit One will not sync with your phone.How the Fitbit Works: You have a few choices on where to wear the Fitbit (typically waist, pocket, chest pocket or bra), and you keep that Fitbit on you for 24 hours. Whereas the Ultra had a built-in clip, this one has to use the included silicone clip. The upside of this is that the silicone is unlikely to crack, which is something several owners of the Ultra complained about. The downside is that the Fitbit could possibly come out of the silicone case if the case were to get pulled on clothing or some other object. Whereas you used to be able to buy a lanyard to secure your Ultra, in the case of the One, you would only be securing the silicone case and your Fitbit would be lost. Time will only tell whether the silicone case idea is an actual improvement over the Ultra's design.On receiving your Fitbit, there's a booklet says to charge your Fitbit for 5 minutes. The charge is supposed to last for about a week. When the Fitbit battery is completely depleted, charging is to take approximately two hours. If you're like me, you'll find yourself just popping the Fitbit into its charger whenever you know you'll be sitting at the computer a while. Unlike the Ultra, which used one USB port on your computer, this Fitbit will use two: One is a small piece that communicates wirelessly with your Fitbit. The other is what I believe people are referring to as a "dongle" -- it's a USB with a short cord: You snap your Fitbit into the end, and that's how the Fitbit charges.I should also mention installing and pairing the device was virtually hassle-free. Since I was upgrading the Ultra, I just synced my Ultra by putting it in the cradle and then unplugging that USB. The instructions for the Fitbit One are clear. You download the software from their web site. Pairing the device with the software on my computer was easy. I was asked what kind of device I was pairing as well as whether I'd still be using the Ultra.What will the Fitbit One do? The Fitbit One is a very accurate step counter. It also shows calories burned and distance walked. There's a cute (not too girly, guys) flower that you make "grow" the more activity you do. And it tracks your sleep. The included wrist band attaches with a very fine Velcro-type material, making it a perfect size for men and women. This Fitbit One wrist band also has holes in it apparently to help ensure that the band doesn't feel hot on your wrist. Included in the band is a little pocket. At night, you slip the Fitbit into the pocket and press and hold the button, which puts the Fitbit in sleep mode. You have a choice between normal and sensitive setting, adjustable from the web site. When you awake, you just press and hold the button again to tell Fitbit that your sleep time is over.New to this Fitbit One is a silent alarm function. Basically, you can set vibrating alarms from either the Fitbit web site or from your Bluetooth-enabled phone. When I tried it out while awake, it was a soft little vibrating that I commented was as likely to wake me as "an ant wearing socks, tiptoeing across the floor." But I kept a (somewhat) open mind and still set an alarm for 7:30 a.m., which would give me enough time for an 8-hour sleep. Much to my happiness, I awoke to the soft little vibration on my wrist. My assessment on this is that I know that if I'm particularly tired, sick or know I'm going to get less than 8 hours of sleep, I cannot trust this as I've had to set an alarm across the room sometimes to wake up. If I have to be up early for something important, I will still need to set a traditional alarm. Depending on how deeply you sleep, your mileage may vary.Once you press the button to indicate you're trying to fall asleep, the Fitbit begins recording sleep data by noting how often your wrist moves. Wrist movement is interpreted as awake time. On the web site, this information is reflected as a sleep efficiency percentage. Now, it's not extremely accurate, because Fitbit doesn't know the difference between your lying there still and your being asleep. However, you'll probably realize soon that if you're lying there, reading a book, just move your hand every one in a while. Later, in the morning, you can adjust your sleep times through the web site to cut off any unnecessary activity at the beginning.What is Fitbit Not Good at? It's very step-oriented, so that means it's not going to accurately record your use of an elliptical machine, Pilates, weight lifting, rowing machine, swimming (don't get it wet!) or anything else that doesn't result in a typical stepping motion. However, you can manually record these activities on the web site, and it will overwrite the data for that period of time. I am finding that the web site food database is still inferior to other sites like MyNetDiary or Lose It, particularly since those allow scanning of barcodes for easy recording of food intake. However, a happy discovery is that Lose It can sync with Fitbit's web site, so I can record my food on Lose It rather than doing so through Fitbit's site. This is a good time to mention that there are also many other apps that Fitbit has partnered with that will sync your data.As with the Fitbit Ultra, the Fitbit One will:---Count stairs climbed (hills count) and translate those into floors. It's just one more way to challenge yourself. On the web site you can earn badges for how many stairs and floors you've climbed. The site also gives you interesting little messages about what that climbing equals, such as "you've just climbed the world's tallest snowman," and if you're the curious type, you can click the message to learn more.---You've got a clock! Just press a button at your waist and look down to see the time.---There's a stopwatch. Training for a race? Just trying to beat your previous times? You can use the stopwatch to record an activity.---Righty and lefty friendly. I'm right-handed, but I like to wear the Fitbit at the left side of my waist. The words were backwards, but I learned that through the web site I could change the direction of the words.---Give it a name. You have 8 characters to input a name or other info. That's not enough for a full phone number with area code. However, you if you search the Internet for "short email address," there are a number of email address services that would fit that 8-character allotment and allow you to forward any email to your regular email address. This might come in handy if you (heaven forbid) were to lose your Fitbit.---Friendly little chatter. So you're sitting on the sofa and you realize you should really get up and move your body. You stand up, and a blinked message catches your eye: GO GO GO or Hello! or I LIKE YOU. I found this annoying after a while, and I disabled it through the web site. Through the web site you can actually disable any of the features you don't want to see on your Fitbit.Is the Fitbit One Smaller Than the Ultra? Yes and no. As mentioned, the One fits inside a silicone clip. You really don't want its slippery little body moving around in a pocket, so you'll be using this clip. With the clip, the Fitbit One is actually larger than the Fitbit Ultra. Without that silicone clip, it is, indeed, smaller. Please check out my photos and you'll see a size comparison.As I stated on my Fitbit Ultra review, use of the Fitbit web site is 100% free. In fact, you can start using it before ever owning a Fitbit device. That's what I did before my previous Fitbit arrived. The site has an active Community of users trying to be healthier as well as device support. If you have questions about the Fitbit, I think the forum on the web site is probably going to get you a faster answer than emailing the company.So over a year later, after starting with Fitbit, owning and wearing a Fitbit has been one of the best decisions I've made. I went to a Quantified Self meetup, and one of the users asked why I'm still wearing the Fitbit if it's already established a habit of exercising. The answer is this: The Fitbit allows me to add gamification to something I don't enjoy (exercise!). It challenges me to reach my goals. If I have a period in which I've gotten few steps, I feel an internal nagging that I want to get that number back up where it belongs. It helps me analyze my sleep and see how that affects other factors in my life.After writing the update on my previous review for the Ultra, I actually DID re-invest in the Premium membership (49.99 on the web site) in order to get the Trainer feature back. I needed some help with goal-setting, and I wanted to be able to download my data in a CSV format. The fact that you cannot download your data without the Premium membership is a small annoyance to me, as I believe you put that data into the site and deserve to be able to download it without paying for a Premium membership. Another disappointment is that the custom trackers that I created through the Premium membership are not included in the CSV download. However, overall, I'm back to finding that Premium membership adds enough value that it's worth it to me. I'll have to reevaluate this when it comes time for renewal (be sure to disable auto-renewal if you don't want to be charged automatically). So again, no, you don't have to pay anything to use the Fitbit web site and get the basic features. The Premium membership just adds some extra perks that you may find helpful in taking your health to the next level.Has Fitbit been a fast way for me to lose weight? Nope. I lost the 30+ pounds over a period of a year. However, it's been a painless, sane and lasting way to lose weight. I attribute the weight loss to the awareness the Fitbit has brought me. Because I'm more aware of my activity (or inactivity), I just naturally make better decisions on a daily basis. If you're motivated to do so, you could lose weight quickly with the Fitbit by always tracking food intake and energy expenditure. I've found that making a gradual and permanent lifestyle change has been the best for me. I can't wait to see what new goals I'll be reaching for and achieving over the next year!UPDATE in MAY 2013: Please note that Fitbit now reportedly works with more than just the iPhone. I also wanted to let you know that I'm still happy with the Fitbit and wear it every single day. However, this one has nearly been lost on a few occasions due to the silicone case getting caught on clothing, causing the Fitbit to flip out. I am a very fastidious person who is careful about things (always puts my keys in the same place, etc.), so if this is an issue for me, it may be for others. I wish they hadn't changed the holder, but I understand the need to since the previous version was starting to crack at the stress points. IF this is a big concern for you, I would recommend preordering the FITBIT FLEX, which is one you wear on your wrist. The upside is that you'd have it on 24/7 and can wear it in the shower, etc., and the downside for me is that I don't want to see it on my wrist every day. Hope this helps anyone trying to make a decision. Again, I'm very happy with the Fitbit One, but I am having to be very careful with it to prevent losing it.UPDATE in DECEMBER 2013: My Fitbit had its first structural failure this month, and I wanted to update you with the problem. The silicone case has a place on it where two pieces are attached. This is the side that slides into your clothing, making it a weak point. One day I noticed the two pieces separating, and I pushed them back together. The other day I pulled my Fitbit out of my pocket and found the small piece was missing. Thankfully, later I found it and will try to glue the two pieces together. That section is a poor design because it's under stress when you remove the Fitbit from your clothing. I've added a picture above showing the two pieces. As far as whether I still love the Fitbit, yes, I do; however, I still think the silicone case is a poor design. There have been numerous occasions where I've almost lost the Fitbit due to it popping out of the silicone case. Hopefully, the company will improve on this design in their next release.

I got my Fitbit One on May 29, 2013, so I've had it for 2 and a half months. I wear it all the time except when I'm showering.

Quick Spoiler Alert: I Love My FitBit! It's my little Jiminy Cricket Conscience, reminding me to be more active.

Fitbit is really tiny! The pictures don't show how small it is. It's smaller than my thumb. The clip that is built into the holder feels like strong sprung steel, so it's pretty secure. I wear mine on my bra, but you can also wear it on your pants. I used to have old fashioned pedometers that would come off at times, especially in the restroom when it would get jostled around a bit. If you decide to wear it on your pants, you can always get a little tether, which would be nice insurance.

When I put it back on after a shower, it says Hi! I know that's sort of silly but it still makes me smile. It's a nice, friendly touch.

I use the included wristband to wear it at night to track sleeping. The wristband is pretty comfortable, but I've had a problem with the velcro. It's not like regular velcro, and doesn't hold as well after a couple weeks. I've just sewn on stronger velcro on top of the strip and it's totally fine. Also the Fitbit has slipped out of the little pouch (which is made of thin fabric so you can read it while on your wrist if you want). I realized recently that instead of sliding it into the pouch and having the end near the opening, I turn it 90 degrees so it is parallel to my wrist and doesn't come out while I sleep.

I use a separate phone app to track my sleeping as well. The phone app is pretty amazing, but honestly, the Fitbit is rather accurate too, just in a different way. I've had a couple issues with it. If I reach over to pet my dog while I'm falling asleep, using my left hand (you wear it on your nondominant wrist), it counts the movement as actual steps. And when I am trying to fall asleep, I usually force myself to lie very still to help me relax. But I'm afraid Fitbit will think I'm actually asleep. So every few minutes I'll slightly move my arm to tell it I'm still awake. This seems to work.

One thing I've learned is I actually usually fall asleep much faster than I had realized! This was really helpful, since I have insomnia. Basically for sleep, it decides if you're asleep, restless or awake. It tallies all of this for you, which can really give you a lot of information. My app is way more complicated, but I still use it for a few of the charts. But if you need basic information, this is perfect. I'd be okay with just having the Fitbit, if I weren't such a numbers geek and into quantifying myself. :P

One more thing about sleeping, you have to tell Fitbit when you are in bed and ready to go to sleep. To do this, you just push the button for a couple seconds, until the timer starts counting. Then when you wake up, you push the button for 2 seconds again to tell it to stop. For the first little while, leave yourself a note so you get in the habit of doing it. After awhile it's no big deal at all. And if you forget, you can tell Fitbit when you were asleep, so it's pretty forgiving.

For counting steps, it's as accurate or more so than old fashioned boring old pedometers. I am quite pleased with it. Make sure to set your step length and fill out your information! My mom got one the same time I did and she didn't bother, and it was way off. It only takes a few minutes to set it up properly and the directions are pretty easy.

There are issues with stairs, though. I have a single flight of stairs down to my garden. I like to walk up and down and up again to do several flights of stairs in a row. Fitbit uses an altimeter to figure out you're going up stairs, so I guess it gets a bit confused if you go up, then down, then up, etc. The way I found around this is to add about 40 steps out into my garden at the bottom of the stairs before going back up. This works most of the time, but sometimes, alas, it doesn't count all the flights I take. It's better than a regular old pedometer though, by far! One other time it was inaccurate was when we drove up a mountain and then hiked up and down really steep trails. It thought I was going up lots of flights of stairs, which was fine. It counted my steps, but the estimation of the flights of stairs seemed way off (overestimated). You can go in and manually correct it on your log though. It's not perfect, but it's the best I've found so far. Also, driving up the mountain threw it off too. You can get an app for Android that you tell it when you're driving, and it tells Fitbit, which is handy. Get it if when you drive it thinks you're taking steps. I don't have this problem normally, but driving up steep hills seems to be an issue, easily solved with the app.

When you want to exercise during the day, you can tell Fitbit. This is helpful and makes it more accurate, so right before you start, push the button for 2 seconds to start the timer. Then push the button again for 2 seconds to stop it when you're done. Then go tell Fitbit what exercise you were doing.

There are several screens you can scroll through on the Fitbit. The last one is a flower. As you take more steps during the day, you get more leaves on the flower. It's a nice little graphic that is kind of sweet. Don't worry, guys, you won't lose your Man Card for having one of these. FitBits are so awesome. You can talk QS (Quantified Self) stats with all your friends!

To sync up your Fitbit, you put a little USB dongle in your computer and usually it syncs itself. I think it seems to sync, when you are within about 15-20 feet of the dongle, about every 20 minutes, but that's a rough guess. If you want to force it to sync (to set a silent vibration alarm, for instance- go to Settings on the web interface), you can do that. Fitbit has great directions for everything. Sometimes it gets confused about syncing. Taking the dongle out and putting it back in helps, as does forcing a sync sometimes. That has fixed it every time for me.

Now, about the web interface. You go to Fitbit.com, register to get an account, and you get a dashboard with all kinds of dials and widgets. It's pretty intuitive. The beta version is much prettier than the regular, so you can use it instead. Make sure you set up your account, settings and all that good stuff! That is how Fitbit knows how many calories you are burning, etc.

The great thing about Fitbit, and I did a lot of research before buying one, is that you can actually connect it to all kinds of different apps and other sites. Endomondo is a great one, and MyFitnessPal is invaluable. You'll see all the different ways to connect on the website when you are logged in.

If you use MyFitnessPal, which I highly recommend, you will log your food and exercise in MFP, NOT Fitbit! The interface for food is much more intuitive and easier to use in MFP. It's also easier to put in your measurements and weight in MFP. The account is free and they work beautifully together.

There is another website called FitBolt that I learned about, I think through Fitbit. It's pretty neat, but the interface is a bit buggy and requires some patience. If you work at a desk, every 40 minutes (editable), it tells you to either stretch or do an exercise. You can choose either or both. I work at home, so it's easy to do 30 seconds of plank or pushups, but I guess for some it's not practical. But the stretches are meant for people stuck to their computers. It connects to Fitbit, and after you tell FitBolt that you did the exercise they suggested, they tell FitBit and you get credit for that, and Fitbit will tell you how many calories you burned. Then MFP will tell you how many extra calories you earned! They all work together. Endomondo also works the same way. Just make sure if you log an exercise in one app that you don't then log it in another. Let them talk to each other and Fitbit will work it out.

Ok, so those are the details of how to use it. But do I like it? Do I actually use it?

You bet I do! I love it! It's very motivating. I hardly ever look at my Fitbit itself except when remembering the exact minute I start an exercise so I can log it in MFP accurately, when I then have FitBit use the timer. Mostly I have FitBit open in a tab in my browser, and MFP in another tab so that they are in my mind. It's so inspiring when I am active! And when I am really sedentary (it's so easy!), I can see that in the charts. So then I'll go do some jumping jacks or run up and down the stairs or something, anything, to get in some activity. So it really STILL keeps me motivated. Seeing those charts and getting rewards for the first 10 flights of stairs in a day, is awesome.

Oh! And there's a social aspect to it as well! You can become friends with other users and have friendly competitions to see who can take more steps in a day or week. That's really helpful for some people. I find it helpful to have a FitBit buddy.

For the price, this tiny little thing is just awesome. Yes, it sometimes gets confused, but less than a boring old pedometer that does a heck of a lot less. The sleep data is really nice, too, which is why I got the FitBit One. If you find data motivating, and want to see your progress on nice charts, get it and let it motivate you to move more.

My mom has one, as I mentioned. She doesn't use all the features (like sleep) like I do, but she also finds it motivating and will take the dog for a walk just to get in steps. She's in her late 60's and anything that keeps her active is well worth the money! And the same goes for me!

Update 9/2/16: Years later mine is still going strong as well as my husbands. However he left the household leaving it behind so I was able to set it up for my teenager daughter to use it and it was an easier process than I thought it would be.

Not only did I buy one for myself, but after seeing it in use and how it could motivate a person my husband asked to get one as well so we purchased two from Amazon about a month apart. Both times this item shipped quickly with my Prime account.

I do read that some reviews say that all of the numbers are skewed and incorrect, but after reading lots of online reviews from different products of this type both on this site and on other websites NONE of these devices are 100% accurate for anyone...and anyone who says so is probably just not aware or lying to themselves or you because they are brand loyal. I've had no issues with it miscounting major steps or stairs. I did notice that it does sometimes count steep hills as stairs, but I think it works on altitude so that makes sense. And honestly, who cares...count it I worked hard to get up that steep hill count it! :0) I would be interested to find out how many stairs it counts as a flight, as I seem to rack up more flights at work than at home. I think my work staircase may be steeper or go higher than my home staircase because I always get more flights while at work than at home even if I only go up them once at work. Also it only counts going up, not down. Again that is understandable because your muscles work harder going up.

As for counting how many steps my feet take each day I clip mine every day to the inside of my bra in the gap between cleavage. I'm not sure that would work for all women, but it works perfect for me and I have never had it come unclipped and should it accidentally it would fall into my bran and I wouldn't lose it. The instructions say you can clip it to your waistband or put it in your pocket as well. I was afraid of it falling off and losing it, but I think the clip would be strong enough to keep it there with no problems. I'm just used to putting it where I do now. I liked the location so much that my husband decided he liked the location too, but being a man with no bra he got creative. We had an extra lanyard around that has a keyring that a badge clip was attached to. He took off the badge clip and now he just slides his fitbit clip onto the ring, puts it around his neck and slides it under his shirt. The shirt keeps it close to his body so it's not swinging around and still gets an accurate count. We've compared our numbers when waking around together and they are always very close, slightly off because we have different strides. He's also worn both, one clipped to his lanyard and one to his waistband and he got the same numbers on both after a walk. So we feel that him using it this way is okay.

I've also seen reports of people saying it's sensitive and picks up things like wiggling around, driving/riding in a car, etc. I've watched mine and I've not seen it add extra numbers for any of these types of activities unless I was actually moving my feet. It did count dancing if I was moving my feet and stepping around, but if I was just swaying in places or wiggling my hips/upper body it did not count any of that. I've even stood and shook the thing and if I shake hard enough I can get it to count numbers, but I had to do it pretty vigorously.

I bought it for the steps and stairs, so these are the features I use most. I did think the sleep function was interesting, I wasn't getting it for that but now that I am seeing my sleep tracked it has helped me to notice patterns where some days I might not have been sleeping enough. I like how it will still track your sleep as long as you are wearing it even if you forget to set it before you go to bed. If I forget I can just go to the app or website and tell it what time I went to bed and what time I woke up and up pops my sleeping data for that missing night.

The website was a little hard to use at first, it took some learning and just clicking on things to figure out how it worked so for people not proficient in computers they may have a hard time using it. I use the app on my iPod so I use the iPhone version, my hubby has a Samsung Tab 3 tablet so he is using the Android version. They are both different looking, but have similar functions and are pretty simple to use. There are a few things you can not do on the mobile apps that you have to log into the computer to do but it is not too much. Mostly a few setting options and setting goals are unavailable on the apps. I do like how the app will have a battery indicator you can check and the website will send you emails reminding you when it is time to charge.

These both came with dongles and I have both plugged into the computer. When I first set up the second I had to have one of the kids take mine to the other side of the apartment so that it would pick up the new one, but once that was one they are both syncing and functioning just fine on the same computer. As long as the computer is on, our information stays pretty current and if we did want to push a sync to see info we can do that as well. I can not sync mine with my iPod but it is because I have an iPod 4 and it's blue tooth connectivity is not as good as the newer devices so not the fault of this product but rather the fault of my device. My husbands however can sync just fine via blue tooth which is nice if we go on a trip and want to get updated info without carrying our dongles with us, they are small and I would be scared of loosing it!

The wristband for sleep is a good size and made well to change size for different people. We both have larger wrists and it's plenty big with a bit of room to spare. The way it is made with velcro it can easily be sized down to a smaller wrist as well so those concerned with wrist size I think would be just fine. It works on velcro and not buckles, snaps, strech, etc which is sometimes a hassle to get the sizing right on.

There are also options to track your food, calories and other exercise. I do occasionally log other exercise, but often I forget to log food, water and calories. If you are tracking calories the device itself will tell you how many calories you are burning, the website is where you would track weight, food, water intake, and exercise. You can also track some other numbers on the website if you are tracking blood sugar for diabetes, blood pressure, etc. So there are options on the website I don't use. Lastly this device syncs nicely with lots of other fitness websites so if you don't want to use the Fitbit site and trackers you can sync it to another website. It is a process however because somethings you can sync via the Fitbit site/app and others you have to go to the other websites/apps and sync through them. So it was a learning curve on that so again someone with little technology skills may have difficulty with this. Lastly you have a profile on the Fitbit website and you can make it public or private letting your friends see various things. I like having the options to make decisions on each thing. I don't mind strangers seeing how many steps I take each day, but I don't want anyone but friends seeing weight and no one cares what I ate if I was tracking food! These are all settings on the website to make certain things visible and others not. There is also an online community that you can use, but I found it clunky and more annoying than anything. Some of the other fitness websites are better so I rather just sync my info and use those.

Overall I think it was a great decision to buy these for both of us as it's increased both of our fitness. I know I can never get in as many steps as he does right now, but it still allows us to be competitive and also challenge ourselves. I know there are days that I forget it at home and multiple times I'll say things like ohhh man I'm not getting credit for these stairs today. (or walking a lot, etc.) It is also good at showing us how some days we feel very active, but are not as much as we think. And other days we feel like we didn't do much but were super active. We find ourselves parking further out just to try to get a few more steps in, or taking the stairs instead of an elevator just to get more stairs! I am really surprised by how it's changed my point of view on things!

I'm not a fitness guru, I don't have a regular workout or exercise routine, and I don't walk a bazillion steps a day. So don't think this is just for those people or the super obsessive. This is a great little device to give you that extra little motivation that might just be the difference between no activity and some activity!

5.0 out of 5 stars Best Fitbit Device Ever!
Reviewed in Canada on May 27, 2019
I have gotten several Fitbit devices over the last decade but I keep coming back to the One. I am disappointed that Fitbit decided to discontinue this product as it is the only reliable device that does not need to be worn on the wrist. I love the One so much that I got one for my husband who also stated that he was tired of wearing a wrist-tracker. Other great features about the One are that the battery lasts almost one week, it takes an hour or less to charge, and it is so compact that it can easily be clipped onto a bra, or put in a tiny pocket and it even tracks floors - great incentive to take stairs over escalators and elevators!

5.0 out of 5 stars Il mio fido amico validissimo
Reviewed in Italy on July 22, 2017
Sono molto soddisfatta del mio nuovo amico. E' sempre con me, anche in casa. Leggerissimo, discreto, non ti accorgi di averlo indosso. Fa il suo dovere egregiamente: molto preciso come contapassi (anche se consiglio di mettere lunghezza camminata 70 anziché 71 come di default altrimenti ne conta meno, ma se abbassi a 68 ad esempio ne conta davvero troppi), i piani saliti li conta quando riprendi la camminata (non conta i gradini), le calorie le brucia anche a riposo (giustamente respiriamo...), la distanza percorsa immagino sia calcolata sui passi effettuati. Non viene fornito con un libretto d'uso. Indispensabile l'app Fitbit (molto ben fatta, completa e di facile intuizione) disponibile gratuitamente per ogni cellulare, da lì hai un pannello che si aggiorna via bluetooth (a volte fa un po' fatica e devi riavviare) appena apri l'app direttamente con l'One. Possibilità di calcolo di quanta acqua bevi, di cosa mangi (addirittura con scansione del codice a barre dei prodotti) e di allenamenti mirati di pochi minuti. Tutti gli obiettivi sono modificabili (ad esempio puoi anche mettere 3000 passi al giorno). Dopo un po' non riesci a tenere conto di tutto (sopratutto per cibo ed acqua), ma rimane un validissimo aiuto motivazionale per il movimento. La fascia per la notte è molto leggera e non ti accorgi di averla, ma anche per quella dopo un po' vuoi stare libero (anche se il "contasonno" è preciso e calcolo tempi di addormentamento decurtando i risvegli dal sonno profondo, quindi dandoti veramente il tempo preciso di quanto hai dormito, che è sempre meno di quello che crediamo). In definitiva, il migliore di Fitbit, sopratutto per chi non sopporta cose addosso come i braccialetti.

5.0 out of 5 stars Un motivador estupendo
Reviewed in Spain on April 14, 2015
- Fiabilidad: Hay gente que comenta que si con el coche o la moto les cuenta pasos, es posible que en algún bache te cuente alguno, pero es absurdo... es MUY poco lo que cuenta y por tanto es más que asumible. es muy fiable y que te cuente 10-20 pasos que es lo que hay del sofa al wc en un viaje en vehículo pues no creo que sea un problema.
- Escalones: Me decidí por el ONE dado que a diferencia de las otras pulseras este contaba escalones, para mi sorpresa no cuenta escalones sino Plantas subidas, al principio pense que esto no me gustaba, pero es mucho mejor así, pues por una parte los escalones pueden ser de diferentes tamaños y por otra dado que se basa en presión atmosférica y por tanto "altitud" también cuenta si estas subiendo una montaña o rampa, en resumen este punto también es positivo.
- Comodidad: El llevarlo enganchado en el cinturón es muy practico y discreto, quizá con una pulsera te olvidas más de ir cambiando de el de un pantalón a otro, pero dado que las pulseras no miden altitud sigo contento con la compra.
- Sueño: Se basa en los movimientos y es muy curioso ver esta información, con el pack que compras te viene la pulsera para atarlo cuando duermes que es muy cómoda.
- Experiencia: Si a registrar los pasos y plantas subidas le sumas anotar lo que comes con la web de fitbit... puedo asegurar que la motivación es máxima, al principio era reticente al tema de anotar lo que comía por tema de tiempo.. pero una vez lo haces te acostumbras y va muy bien, lo cierto es que no solo he bajado mucho peso si no que estoy mucho más activo ahora.
- Social: Fitbit te permite compartir retos con otros amigos que dispongan también de fitbit, por ejemplo tengo un par de amigos que cuentan pasos con Iphone y otro con fitbit, compartir los retos parece mentira pero es una motivación máxima.
- Precio: Creo que todos estos dispositivos tienen un precio un pelin elevado, no obstante la tecnología que llevan dentro es muy precisa, en algunos post de internet se les critica pero imagino que son versiones muy antiguas.. pues la preciosion la he notado muy aceptable.

- Algo negativo: Seguramente en unos años los smartphone cubrirán toda esta tecnología (pasos+escalones), pero si quieres motivarte ya HOY es un gadget muy interesante.

5.0 out of 5 stars Parfait pour se motiver à bouger, que ce soit pour perdre du poids ou se maintenir en forme
Reviewed in France on September 22, 2014
Un rapport détaillé, après un peu plus de 3 semaines d'utilisation:

Acheté dans une démarche globale de perte de poids, ce petit Fitbit One - pas plus gros qu'une petite clé usb - me permet de quantifier les calories dépensées au quotidien, tout au long de la journée. On se prend vite au jeu de "faire ses pas" en empruntant des chemins nouveaux et qui rallongent un peu la distance, ou en prenant l'escalier au lieu de l'ascenseur.

Au-delà de ce côté ludique qui devient finalement vite une (bonne) habitude, il a une réelle utilité au quotidien en quantifiant les calories brûlées, ce qui permet d'ajuster ses repas en conséquent. Par exemple il s'intègre parfaitement avec myfitnesspal, qui est un peu son mirroir et permet de chiffrer assez finement son absorption de calories. De cette façon, on peut se mettre en léger déficit calorique quotidien pour perdre du poids, ou choisir de se mettre à l'équilibre pour le maintenir, sans pour autant tomber dans des excès intenables dans la durée, trop démotivants, et tout simplement mauvais pour la santé.

Je n'ai eu aucun problème non plus avec les "vraies" activités physiques réalisées en parallèle et mesurées par d'autres moyens. Par exemple les courses à pied enregistrées avec Runtastic (ou Endomondo etc...) ou les séances de natation enregistrées avec une montre Garmin Swim, viennent s'insérer tout naturellement en lieu et place des mesures du Fitbit One dans ces tranches d'utilisation, ce qui ne fausse pas les mesures, en double comptant les calories "sportives" par exemple.

Au niveau du format, je me suis longuement posé la question d'un bracelet (comme le Flex de ma femme) ou de celui-ci. Au final je suis très satisfait de ce choix. On ne fait pas plus discret, je le porte dans la poche du pantalon tout simplement. Juste une habitude à prendre au début pour ne pas l'oublier le matin. Ne portant jamais aucun "bijou" (ni gourmette, ni alliance, juste une montre "habillée" parfois) je n'aurais sans doute pas supporté très longtemps un bracelet "sport", que ca soit au niveau du confort ou de l'esthétique. De ce point de vue, chacun ses préférences. Il est aussi plus riche en fonctions qu'une Flex (altimètre pour mesurer les étages, écran...) et le fait de ne pas le porter au bras évite de compter des pas superflus en agitant les bras pendant une discussion animée par exemple. :)

J'ai eu quelques rares cas où il m'a compté des étages en trop, par exemple une fois pendant un trajet en voiture avec des tronçons très dynamiques sur route bosselée en rase campagne. Mais dans l'ensemble c'est plutôt fiable, et même s'il se plante de quelques étages un jour, c'est sans conséquence significative sur le décompte de calories.

Autonomie: un gros point fort, il tient 2-3 semaines (au moins deux fois plus longtemps qu'un Flex). En fait je l'ai rechargé une seule fois au bout de 10 jours par précaution bien qu'il affichait encore une demi-charge. 12j se sont écoulés depuis et il apparaît encore à mi-charge. Bon point car le but est bien de le porter 24/24 donc le moins il y a de maintenance, le mieux c'est.

Pour terminer, la fonction sommeil et le réveil vibrant: donne quelques indications sur la qualité de ses nuits (accessoirement permet de voir précisément à quelle(s) heure(s) bébé à pris son biberon ou ses tétées, les parents apprécieront...) et le réveil agit en douceur. J'aurais apprécié quelque-chose d'un peu plus sophistiqué comme une analyse en sommeil profond, paradoxal, etc... et pouvoir régler le réveil sur des phases de sommeil, dans une fenêtre temporelle définie, comme le font d'autres appareils. Mais c'est déjà bien pour une prise de conscience du (manque de) sommeil... :p

Au global, très satisfait de ce petit Fitbit One qui remplit parfaitement son rôle, et en toute discrétion.
Une aide réelle pour améliorer son hygiène de vie et se motiver à le faire dans la durée.
