HASH(0x9e2aa600) out of 5 stars A great little gadget - easy and fun - does everything it promises Aug. 5 2010
By Ron Cronovich - Published on
I love my fitbit, but don't buy one! As of October 2011, this model is being replaced by a new model, the Fitbit Ultra, for the same price as the original one.

The Fitbit ultra adds a few features, like an altimeter. But it includes all of the features of the original model, so everything I wrote in my review applies to the new ultra model.

I got my fitbit in early 2010 and have been using it on and off (mostly on) since then. I am very happy with it and highly recommend it. It's an easy and fun way to track your activity levels and estimate calories burned, and it should appeal to fellow gadget lovers.

The device weighs under one-half ounce and clips securely to clothing. I'm paranoid about losing stuff (justifiably so), so I keep mine in a little USB drive holder with a clip.

It has an accelerometer chip, like most smart phones, iphones and other gadgets, which can measure its movement in three dimensions.

At any time during the day, you can push the one little button on the fitbit to display an estimate of calories burned, steps taken, miles walked, and a graphic of a flower that grows more petals as you're more active.

When you're near your computer, plug the included fitbit receiver into a USB port, and the receiver will wirelessly collect data from your fitbit tracker, then send the data to the fitbit website. You use this website for most of your tracking and analysis. (The only software you load on your computer is a driver/client for the receiver that plugs into your USB port.)

I find fitbit very accurate for estimating my walking (number of steps and total distance), calories burned, and activity and intensity levels. While these are just estimates, they're pretty good estimates, and they take into account my age, height, and weight. As the data accumulates over time, you can identify trends and measure progress in your fitness regime.

Some people complain that the fitbit system makes you use its website rather than providing software for your computer. I actually prefer it this way. For one, the website is extremely well designed and easy to use. Second, you don't have to worry about using up your hard drive space (an issue if you use a netbook, ipad, macbook air, or older laptop), and you don't have to worry about downloading updates when the developers issue bug fixes or add new features - these just show up at the website without requiring any effort from the user. Third, this way keeps the cost down. Fourth, you can access the fitbit website from any computer with an internet connection.

The website shows graphs of your activity levels and calories burned throughout the day. At this website, you can also enter specific activities you do (like bicycling, working out at the gym, etc). You have to enter these manually, but it is very easy to do so and it's very useful to have a record over time of the specific activities you do.

The website also lets you track your eating. I didn't start using this feature until just recently - I thought it would be too much of a bother. However, I see now that the website makes it very easy. For instance, as you start typing a food (whether from the grocery store or a chain restaurant), it'll suggest a bunch of near-matches from its (extensive) database. You can click on one of these near matches, and it'll fill in all the nutritional info. I force myself to be very honest and complete, even when I break down and gorge on unhealthy comfort food. Keeping a record makes me aware of what and how much I eat, and keeps me honest. And I'm less likely to order a desert after dinner if my log shows that I've already eaten a few deserts this week.

You can also wear the fitbit tracker when you sleep (you slip it in a cloth wristband that comes in the fitbit package). In the morning, sync the data from the device to the fitbit website, and it will keep a record of when you went to bed, how long it took to fall asleep, how often you woke up during the night, and what time you woke up. It tells you your "sleep efficiency," which I think is the time spent actually sleeping as a percentage of time spent in bed. I do not find the sleep data as accurate as the other data fitbit measures (like walking and activity level while awake). For example, it'll say you took 8 minutes to fall asleep when you know that you really took at least 20 minutes: if you lay still enough, fitbit thinks you're asleep. Yet, I find the sleep data interesting and useful enough to keep wearing my fitbit to bed every night: with virtually no effort on my part - fitbit keeps a record over the long term of how much sleep I'm getting and the quality of that sleep, even if the measurements are somewhat noisy. This allows me to identify trends, and if I get sick or feel tired during the day, I can get a sense of whether it might be due to not getting enough quality sleep.

The fitbit is not perfect and cannot do everything. It cannot tell when you're bicycling, or how hard you're working when you're bicycling. While a little sweat or rain shouldn't hurt it, it's not waterproof and shouldn't be worn when swimming.

But fitbit doesn't promise to do everything. It promises to do SOME things (like estimate how much you walk, how many calories you burn, record your activity level at each time of day and let you identify trends). And it does what it promises very very well, in my experience. The device and the fitbit website are well-designed and easy and fun to use, and fitbit completely lives up to my expectations.

At this time (October 2011), fitbit has tons of very positive user reviews. In its early days, there were a fair number of negative reviews, though, but it seemed to me that most people who were disappointed in the device had unrealistic or misinformed expectations when they bought it. My suggestion to you before you order is: visit the fitbit website, read about what it can do, read the FAQ, and maybe google "fitbit review" and look for some reputable reviews (the WSJ has a good one). Then you will get a realistic sense of what the device can and cannot do, so you can make an informed decision. If you like what you see on the website, I'm pretty confident you will be satisfied like me.

I love my fitbit. If I lost it, I'd replace it immediately. In fact, now that there's a newer version for the same price as the original one, the odds of me losing it seem to have increased a bit. ;-D

HASH(0xa046f6d8) out of 5 stars Great in Theory Feb. 9 2011
By C. Kemper - Published on
I am a little over a year into my love-hate relationship with fitbit and to be honest, despite be religious in using it and seeing definite benefits, I really can't recommend it to anyone.

In total, I have had six (yes 6.0) fitbits. Here is our tale:

Fitbit one:
I ordered my fitbit from the company web site in December of 2009 and despite a promised delivery date of early January, I received it in late February. I should have taken this was a sign of trouble, but I am apparently a total sucker. Less than a week into owning it, my fitbit began dying during exercise which pretty much defeated the purpose. I contacted customer support and attempted to get help on their forums, both of which were deplorable.

Aside: Fitbit subscribe to a "we reply to every inquiry in 24 hours or less" customer support policy. This sounds great except that it means that they send you an automated message once a day without any actual resolution to the problem at hand. Reply to their email (even if it is mere seconds after you receive it) and you can count on waiting another 24 hours for a response.

After a week of exchanging increasingly frustrating emails, they agreed to send me a replacement.

Fitbit two:
This one shipped remarkably quickly. Unfortunately, it died in similar fashion, never lasting more than 30 minutes at a time from the moment I received it. By early March, after protracted negotiations with my friends in Fitbit customer service, my third fitbit was due to be sent to me.

Fitbit three:
The third one took well into April to be shipped. By April 14, it died in the same fashion as its predecessors. I again had to do the song and dance with customer service: repeating the problem over and over again only to receive canned email responses that suggest I try the same "solutions" that I have tried in previous iterations all the while I supplicate myself in hopes that they will deliver a working version of the product that I paid for. At the end of the day, that winds up being a bit humiliating and maddening. A little over a week later fitbit number four was on its way. For those of you keeping score, I am now a good five months into my fitbit experience and have gotten *maybe* two weeks of use out of the collective lot.

Fitbit four:
I will always look back fondly on good old number four. It served me nobly for three months before kicking the bucket and even survived some protracted athletic endeavors, a feat never achieved by any before. Sadly, by the end of July, it too stopped working.

Fitbit five:
At this point, I am a bit surprised that Fitbit continue to humor me, but they went ahead and sent me number five after number four bit the dust. The demise of number five was entirely my fault. I decided to take a dip in the ocean while on vacation in Mexico and completely forgot that I had it on. Surprisingly, it kept kicking for a good two weeks after the bath, but finally couldn't hold a charge for very long. At this point, it was a matter of principle, so I actually ordered a replacement at my expense (I figured the Fitbit had spent at least the cost of a unit in just shipping me replacements, so I couldn't let this drama end with a mistake on my part).

On a lark, I asked my good buddies in Fitbit customer service if there was any value in sending my soaked Fitbit back to them since it's sitting in the house was a constant reminder of our failed relationship. Astoundingly, despite my full disclosure of having brought this on myself, they offered to send me a replacement. I accepted their offer which means that I now am on number 6 with number 7 (the replacement I purchased) waiting in the wings.

Aside: By now, the customer service seems to have improved quite a bit ( and I say that not because they keep sending me free replacements) my last go round with them resolved my issue in a matter of hours; a significant improvement over the days and weeks it took previously.

Fitbit six:
My sixth fitbit arrived around Christmas 2010 and it has held up thus far (it is now early February 2011).

Despite my many issues, I actually do like the product...when it works. I am a bit of a data junky and it fills a gap that few other products can and requires minimal effort on behalf of the user. Aside from the problems with it not working altogether, I have never had a problem syncing to the web site and the web site is competitive with comparable sites targeting the fitness market (especially now that they have an improved mobile version). I can't say that I do or would use the food tracking portion on a regular basis, but it is passable. The community aspects are nothing more than a forum.

Things are not all rosy even now. We all have our faults and my fitbit does occasionally fail to track my sleep. I can't really explain why, but it is easy enough to fix on the site after the fact. I have also begun to suspect that it may not accurately count strides (which is its raison d'etre, and thus very disconcerting). I used it in conjunction with an elliptical machine which also tracked strides. I have to assume that the elliptical is accurate in stride count based on its design, but when I was done with my workout the count on the elliptical was 2,000 more than the fitbit. That represents a more than 20% margin of error, which is pretty much unacceptable.

Sorry for the long and rambling tale. Perhaps if you had the patience to wade through to this point, you have the patience to deal with this product and the company that makes it. The bottom line is that when you track your activity and set goals you think twice when, for instance, choosing between the stairs and the elevator. Fitbit has definitely helped me make those small changes and to focus on being as active as possible, perhaps that's why I keep coming back.

HASH(0x9ed36528) out of 5 stars I love my Fitbit! April 5 2011
By Carla - Published on
I purchased a Fitbit on January 29, 2011. I needed something new to keep my fitness routine interesting and thought that a new gadget might do the trick. I was totally blown away by this little techie gadget that I discovered -the Fitbit. After 2 full months, I'm still in love with it. Here's my list of pros and cons:


1. Convenience: Unlike previous pedometers I've owned, I don't lose the FitBit, I don't misplace it and I don't have problems with it missing some of my activities. I wear the thing 24 hours a day. During the day, I clip it to my bra and at night, I clip it to the armband that came with the gadget.

2. Accuracy: I've tested it against the distance of my gym's running track - it is very accurate and I didn't even have to change the default stride length.

3. Motivation: I've been a fitness nut most of my life, but due to an avalanche of health issues, I had gained quite a few pounds and was really feeling my age. In the year prior to getting the FitBit, I had lost 40 pounds but was getting bored. The FitBit gives me an instant assessment of my daily progress toward my fitness goal. If I'm near the computer I have it synched to, I can go online and instantly see where I am. If I'm out and about, I can click the counter on the Fitbit to see how many steps I have completed and calories burned.

4. More than a pedometer - I really love the whole program you get with Fitbit. I used to belong to Weightwatchers so that I could track my fitness activities and my food intake online and on my smartphone. Fitbit offers me the same flexibility and actually has a fairly comprehensive food list, plus the ability to add more of my favorite foods. As a techie, I really like being able to graph my calories in and out and compare to norms for my age and fitness level. Several activities in my regular fitness program cannot be tracked with a pedometer. I swim about 5-7 miles a week and bike about 30 miles/week and I really like that FitBit lets me enter that activity into my overall daily activities - I am not limited to the counts from the Pedometer. FitBit keeps me honest though, on the days when walking is my only activity. I have to confess to spending several evenings jogging in place in order to get my steps up!

5. Stores data for days and days (actually I think the FitBit stores it for 30 days). So, if you aren't near the computer you synch it to - it will store and sync the data later. I've taken the FitBit on vacation with me with no problems. I've even set it up to synch with other computers when I know that I'm going to be away for awhile and just can't survive without seeing my graphs!

6. Battery life - my FitBit has gone for more than 10 days between recharges. I've been VERY impressed.

7. Sleep efficiency - this may be the most confusing thing that the FitBit records and I'm not sure that I fully appreciate the explanation. However, I used the function almost every day for two reasons. I've always felt like I had significant sleep latency - that is, I'd go to bed but could not get to sleep for a long time. Fitbit has actually re-assured me in that the longest sleep latency that I usually record is 20 minutes (it just seems like hours!). It also tell me how long I've been asleep - for an insomniac like me that is important data that I use to try and improve my sleep and increase my target from 6 hours to 7.5. The gadget shows that I wake up a lot and I'm not sure that I quite believe that - but, could be an indicator that I should see a doctor and have a sleep study.


1. This is a techie's gadget. I didn't find it hard to set up, but I like this stuff and I have used a lot of gadgets over the years. I'm also a healthcare provider and I appreciate the science behind the gadget. I had to re-load the firmware once when it didn't want to synch my sleep data after a vacation. I have synched my FitBit to three different computers.

2. It doesn't have an iPhone app - yet. You can use the FitBit mobile site, but getting an actual iPhone App would be an improvement in speed and ease of use - especially for logging calorie intake.

3. You can't buy any of the accessories separately. I'm about to wear out my arm band and I'd like to have another synch cradle to attach to my computer at work (I spend more hours at work that I do at home!). However, as mentioned, the FitBit stores your activity data and downloads whenever you are near the synch cradle, so the only downside of not being able to download at work is that instant gratification of seeing my activity reflected on the computer screen.


I love this gadget. Usually at this point in my relationship with new technology, I've gotten over the initial excitement. I played with my PS3 about 2 weeks, then didn't touch it again for a month. I rely on my iPHone, but don't add much to it anymore in terms of new apps. I look at my FitBit everyday and anytime I'm on the computer, I have the FitBit window to my account open or log in via my smartphone.

HASH(0x9e316ad4) out of 5 stars Good overall, one glaring bug I hope they fix ASAP Aug. 12 2010
By ldm616 - Published on
Overall, I like this little device a lot. It clips easily and securely onto the waistband of my pants/shorts and does a decent job of tracking my steps. The website is a nice complement and the food diary is a plus. Setting it up out of the box is easy. Just follow the instructions to the letter. I see some complaints here about support, but my experience is they respond to posts on the Community section of within a few hours, sometimes less. Email support ( is also responsive. If you use this device consistently, I'm confident you will move more and, if you also use the food diary, eat less.

So what's the bug?

The short version:
The tracker sometimes miscalculates distances, and the website provides no way for you to correct the tracked distance.

The long version:
The tracker only counts steps. It knows the difference between a walking step and a running step. It uses one stride length for walking, and another for running, and then uses them in conjunction with step counts to calculate distance. That's fine until you walk more quickly than usual on a particular day. Or you run a little slower than normal another day. Since your stride lengths on these days will probably be greater or smaller than the stride lengths assumed by the tracker, chances are it will under or overestimate your distance. You'll experience this if you walk or run a known distance and notice that the Fitbit records a different distance.

The website does allow you to create a "logged activity" where you specify activity type, start time, duration and distance. So you could create an activity for a 13 mile run that took you 2 hours 10 mins, for example. So, in theory, you just tell Fitbit that while the tracker recorded a 10 mile run from 6:00 to 8:10, you actually ran 13 miles in the same time period. This would be great if your logged distance overrode the tracked distance, but in my experience it does not. Instead, the Fitbit completely ignores the distance you log and continues to use the tracked distance instead.

If I'm missing something obvious, let me know in the comments and I'll be delighted to amend my review.

HASH(0x9e41981c) out of 5 stars On my sixth unit, going to give up Jan. 31 2012
By Nred - Published on
I really liked this device for the functionality and unobtrusiveness, and when it worked, it seemed to be accurate. The problem is that this device is extremely unreliable--I am now on my sixth unit. The same pattern has occurred--it works fine for a month or two, or even three, then the display stops functioning on the device (but it still syncs), and finally the sync stops as well. I have not had as bad luck with customer service as others here--takes a few days to get a response, but they have promptly sent me new units. The problem is, after so many (this includes both the original and the latest, with stairclimbing) I 'm just tired. I had a bodymedia for a while, but that is much more clunky since you have to wear it on your arm. Good news is that I now have a quite accurate view of how many calories I burn under various circumstances.
