A lot of power, a little device
Monitor your day with the Fitbit One – this tracker aims to empower and encourage you by delivering real-time feedback that helps you be more active. Why not take the stairs instead of the elevator? Or go for a quick walk after lunch? Those steps will add up fast. One tracks steps taken, stairs climbed, distance travelled, calories burned, hours slept and quality of sleep. Powered by Fitbit’s leading-edge accelerometer and altimeter, the One accurately captures all-day activity that old-school pedometers can’t handle. It bases calculations like calories burned on your personal profile – reflecting your stats.

Syncs your stats for you
Fitbit One automatically syncs your data to PCs, Macs, iPhone 4S, and the 3rd generation iPad. All you need to do is sign up for your free account on Fitbit.com and register your device (which you can also do via select Bluetooth 4.0/Bluetooth Smart smartphones). After that, your stats will sync automatically, giving you real-time access to all that outstanding data on your Fitbit dashboard.

Share and compete with friends
Challenge and compete with friends and family on Fitbit.com. In addition to rooting for one another, you can compare stats and see how your progress stacks up.

Log activities, meals & more
Log your food, water, workouts, weight, and more using Fitbit’s online tools. If you’re on the move, use the mobile app to do the same. Our expansive database covers food and activities, which makes logging your info quick and easy. Create a Food Plan to eat smarter. Log an infinite number of activities, from walking the dog to swimming laps. Before you know it, you’ll have a complete picture of your progress.

Fitbit One syncs wirelessly to any computer or select Bluetooth 4.0/Smart devices and tablets.

Helps you get your ZZZs
Fitbit One doesn’t nap, even when you do. Slip it into your wrist band at night, and it’ll measure your sleep cycle. Once the data syncs, graphs on your dashboard will reveal how long you slept and the number of times you woke up, giving you a sleep quality score. Over time, you can apply what you learn to help you sleep more soundly. The One also has a silent wake alarm that gently vibrates to wake you at your desired time, without disturbing your partner.

Paints a picture of your health
The Fitbit dashboard is full of graphs, charts, and tools designed to help you track your progress and understand your health and fitness. The customizable dashboard and mobile app (both free) bring all that digestible data to your fingertips. Knowing how close you are to reaching your goals gives you added incentive to achieve them, sleep better, and aim higher.

Badges galore
We’ll sing your praises and keep you motivated with Fitbit badges for daily, weekly, even lifetime achievements. Each time you achieve a new goal, or “wow” us with your performance, we’ll award you with a badge. But you’ll have to work for it.

Tuned into other apps
To further track your health, you can export your Fitbit data to several popular fitness apps. Some of them – including SparkPeople, Lose It!, MyFitnessPal, and MapMyFITNESS – let you import their data into Fitbit’s dashboard, so you can track and understand your health in either app. Learn more in our App Gallery.

Life-Changing Gadget 2.0 Video Review! I upgraded from the Ultra. You can read my comprehensive review of the Fitbit Ultra at .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…
Fitbit One and why I changed to the Holistic Wrist (Jawbone Up) UPDATE: If you’d like to see my review of Jawbone UP24, you can see it here: http://www.amazon.com/review/R2ZEG4YLT0HZ9Y/ref=cm_cr_rdp_perm (copy & paste if it won’t click)UPDATE: Several people asked me about the Fitbit Flex. I just got one today. I compared it to Jawbone UP here http://www.amazon.com/review/R1CVXEEYIAIR0W/ref=cm_cr_rdp_perm (copy & paste link if not clickable)—A couple weeks ago I received my Fitbit One Wireless Activity Plus Sleep Tracker, Black after a few months pre-order wait. I had it two full weeks, got to know and learn it, and lost it swiftly. The fact that I lost it so easily made me decide to try Jawbone Up– thinking that if I lose my arm, I’ve got larger issues… My review will be a comparison of these two devices for those trying to decide between the two. Early spoiler: I recommend Jawbone Up over the Fitbit One for most people. UPDATE 3/20: Android app is now available as well as the iOS app. My review is based on the iOS app but I do have an android and will try it soon.Hardware itselfThe biggest frustration I had with the Fitbit One was that I wanted to use it for daytime activity monitoring and for sleep monitoring. Using it for both activities included moving the device from my belt clip, taking it out of the rubber clip, putting it in the wrist strap, and reversing this process each day. It felt like a chore after a few days, and some mornings I even forgot to put it back on my belt after showering & changing. These issues aren’t faced with the Jawbone Up because you can leave it on your wrist at all times– even in the shower. No annoying loss, no annoying moving it from clip to pouch to clip, no forgetting it at home in the morning. The Fitbit met it’s ultimate demise after only its second fall off of my belt. It’s so light and in rubber, it didn’t even make a sound when it left me and met the ground. It was never found. Long live my FitBit One on however many belts it ends up on before it’s lost again terminally…Battery Life & ChargingBattery life on the Fitbit One can be as much as 14 days. The Jawbone Up is rated for 10. Both devices include a USB dongle for charging, and charge in about the same amount of time. Both charged fine when I used my iPhone charger to USB for their dongle.SyncingThe Fitbit One bluetooth sync’s wirelessly to an iPhone if you want, or to a PC. The fitbit comes with a charging dongle, a bluetooth adapter– which must be used as it won’t work with most or all other bluetooth adapters already built in to a PC. Plan to use up one or two USB slots for the Fitbit One. It’s not a constant sync– you have to initiate the sync if you want it to sync “now”.The Jawbone Up syncs by removing the cap and plugging in to the headphone jack of the iPhone. At first this felt like it may be a step back from the Fitbit One, but ultimately it’s simpler and I waste less battery having bluetooth activated on the phone all the time. It’s simple, works reliably, and you can sync to multiple devices if you want.WearingThe FitBit One is quite small and the rubber belt clip is smooth and small. Many users simply drop the device in the pocket, but I’m not one to let that happen and risk loss– ironic because I lost it via the belt clip. I also have some belts that it would’t clip on, so I found myself doing creative things like clipping it inside my change pocket.The Jawbone Up is basically a bracelet– and a stylish looking one at that. I found that the fitment guide on the back of the box ran a little large, so I originally bought a medium. After wearing, it felt too tight. I returned it for a large. I have so far been very happy with the large size. I recommend using the print out PDF from the Jawbone site as it clearly marked me as large when the plastic guide on the box made me think medium. They recommend going “up” a size.From a daytime perspective, the wrist band of the Up hasn’t bothered me at all, and actually I see it and it reminds me to move! I never saw the Fitbit One, and thus thought about it less often and had fewer reminders. More about reminders in functions/software!I do wear the Jawbone Up in the shower, and have had no issues with that so far. It feels sturdy without feeling stiff. You can manipulate it by squeezing to fit tighter, looser, reverse which side meets which, etc. It isn’t a “bendy straw” style where it holds shape. It always holds the wrist shape. The rubber on rubber is what lets it grip more or less. It doesn’t feel heavy or annoying.SoftwareAside from the functionality of wrist vs belt clip, the software is really what differentiates the Jawbone Up from the Fitbit One for me. The Jawbone Up software is infinitely more useful, visually appealing and informative for me than the Fitbit One software. The Jawbone software…
Love/Hate relationship (updated review +1 Star) I just picked up a fitbit one yesterday and I must say this little thing really impressed me.It has motivated me to walk more, to climb stairs instead of taking the elevator, and it has also motivated me to watch my calorie intake.The device is pretty accurate. I counted my steps, then i looked at my fitbit one and it was spot on…. unless you drive a lot…So why the three stars?Because if you wear the fitbit while you are driving then your “steps” count will be way off. If the road is uneven or as they had it in their website, car has “stiff suspension” (they had transmission on their website but i think they meant suspension) it’ll start adding steps taken while you are driving. This is a huge flaw of the fitbit device. So my first day with the fitbit I noticed that my steps are over 2000. And when I left my house it was barely at 1000. So they gotta update this or put a feature that has “driving mode” so that it stops counting steps. Because keeping track of the time you start driving to the time you end and then logging it is to much work.But all in all it is a good device. It really has motivated me to be more active.1 month update:I have gotten used to the tracker counting my steps while I am driving and it is really not a big deal anymore. After awhile you just get used to it. Features I Like:- The automatic syncing feature if you are 10-15 feet away. Just recently I lost my fitbit. But when i opened up ‘fitbit connect’ and clicked on ‘sync now’ it would search for my device and it would locate it. So I knew it was somewhere in my room. And with the help of the ‘silent alarm’ I was able to set it, and locate where it was when the alarm went off (it vibrates)- How hidden it is from the world. I usually just put it in the small pocket in my jeans and then forget it about until I need to check it or need to clip on to something else.- The messages it tells you when you pick up the fitbit when it is not sensing movement. The messages the fitbit display really does motivate you to be more active.- Battery life- I usually go for a week and a half to 2 weeks without charging.- The Fitbit holder/clip- I like the feel of it. When I clip the fitbit to the pocket of my shorts when I do Insanity or play basketball,it stays in place really well. Never had it fall out.- That the Fitbit goes together with MyFitnessPal.- The Badges- Also gives you an incentive to be more active. Gotta work hard to get those badges! lol.- Customer Service: I emailed them on a Saturday and they got back to me on Monday (Only open from Monday to Friday). They even had a follow up email to ask how the customer service went.Just a tip (if this ever happens to you): There are times that I was trying to sync my Fitbit but when it would search for the device a message would come up that would say “Device could not be located. Make sure it has enough battery and that the display turns on.” If you ever get that message and do not know how to fix it (I was searching everywhere and was getting very frustrated)then do what I did. Turn it off and then turn it back on. Then it should be fixed and automatically sync again.Oh yeah. And it would also be nice if they can work on making the syncing feature with the android app.I have upped my review to 4 stars. I cannot leave my house without grabbing my Fitbit device. I even had a friend tell me after seeing my device, that if the Fitbit One was out at the beginning of the year he would’ve passed on the Nike FuelBand.
