I've had my Fitbit for a few weeks, and I really love it, even more than I thought I would. It really gives me an incentive to work out. I hardly ever worked out before I got it, but being able to set goals for how many days I should be working out a week, and seeing those days go up as I work out is a simple, but almost crazily effective incentive. I've worked out more in the past three weeks than I had probably the whole rest of the year. I love seeing stats about the exercise I've been doing, even if I'm not entirely convinced that the calories are correct, it still gives me something to compare other exercise days to. I love the heartrate fuction, and seeing it rise and fall depending on what kind of exercise you're doing, and my bpm has steadily fallen as I've done more exercise, which is encouraging to see. I do wish that it would count stairs, but I don't really miss it, and it's not a terribly important feature, just a small thing. It counts your steps on the stairs, just not the floors of stairs you walk up, and the steps are really the most important part. One other thing I wish was slightly better is the battery. I feel like I have to charge it every couple of days, even though the package says that it should work for a full week without needing another charge. Either way, it's not a huge problem, just something I think could be improved upon. It looks great, it works well. and it provides a simple incentive to work out more and to make the active choice throughout your day. What more could a person ask for?

I had seen a coworker's Alta a while back and debated getting one but was disappointed that it didn't do HR. I didn't like the bulkiness of the Fitbits which did measure heart rate. So I started doing research -- trying to decide what features I did and didn't need. I have been using my phone to track my steps and whatnot to this point. I stopped by the fitbit website to see if they had new offerings and there it was. Exactly what I wanted! I ordered 2 (a small and a large) for my sister and myself from Amazon (2 day shipping!) I was on the cusp of small/large and I can tell you that both fit, but as the website recommends, size up if you're unsure. I've attached photos with the small and large slightly up my wrist. I love the size, the band, and the display. I appreciate the sleep tracker, the compatibility with MyFitnessPal, the silent alarms, and reminders. While it can receive text messages, it will only display short messages and truncate longer ones. The text displayed is small. If you get 2 or more messages from a person in short succession it will display the number of messages instead of the actual messages. However, I understand that I ordered a fitness tracker, not a smartwatch and so I am pleased it has text reading abilities in the first place. It does not track flights of stairs, which is okay by me. My phone didn't track them either. I have been comparing the steps tracked with my other step tracking apps and it seems relatively accurate. I'm sure that there are more accurate HR trackers out there, but the convenience of having these things together in one place is what sold me. Random side story: My sister stole my large fitbit the other day while I was doing dishes and threw it on her ankle to see if it would track. Not only did it track, but the HR was consistent with her small fitbit on her wrist. Some people have thought the calories are wildly off. I think they don't understand how Fitbit does calories. In many tracking systems, you will be shown how many calories you burned for exercise. So if you've done nothing and see some level of calories burned, you aren't sure why it's saying that. You do burn calories even when inactive. The overall calories for the day aren't that useful for me because I'm used to the system where you only get calories shown for specific exercise sessions but I've found when it tracks a workout session, those calories are pretty accurate. I love the social aspect of it, and I like that you can challenge your friends for a specific day/week/weekend of steps and meeting your goals. I like the app that goes along with the fitbit. Pros: ~Design! (I can't express how happy I am with this.) ~Tracks HR ~Auto tracks exercise ~Battery Life (I get around a week and it charges fairly quickly) ~Friend challenges and social community Cons: ~Not waterproof ~Cost (maybe prohibitive, but that is the market of fitness trackers.) ~Text messages system (but again, fitness tracker, not smart watch) Honestly, of the negative reviews I've read about this particular item, most of the people who are unhappy didn't do enough research first. You should judge an item by what it advertises it does. So far this has done everything it's said it would for me. I couldn't be happier. I think if you've done your research and this item has the features you have been looking for, you'll be super excited with it, like me. *Edit 6/5* I've had the FitBit Alta HR for a couple months now. I am still just as happy as when I got it. I've lost about 20 lbs since Christmas. It's slow going but the FitBit community has been great. I posted a picture for my first 5k and 90 some odd strangers cheered me on. Reading the discussion area is always positive and motivating. My only disappointment at this point is the lack of waterproofing because I am swimming more often these days. I'm slowly upping my goals and plan to work even harder all summer.

The media could not be loaded. This is my first fitness watch and I love it. I have been looking around for a fitness watch for some time now, I would say at least more than 6 months. If I was going to spend a great amount of money on something I wanted to make sure it was just what I wanted and that I liked it as well as the way it fit. I measured my wrist and i was right at small and large, so I went ahead and went with large, which gives me some 3 more notches to use for it's tightest fit, so the 4th notch fits me perfectly. I suggest if you are just right at the end of a small and beginning of a large measurement, I would recommend going with the large band. I chose the fitbit alta HR because it can still give me my text and call notifications and I was not worried about answering it from my watch or texting back. If my phone is in the other room and I get a call or text, I can see who is calling and read the text on my watch and decided if I want to reply now or later. The functions of the watch are great, easy to use, and scan through right at your wrist where your stats are at. I love that this watch is on the smaller side, it is not bulky at all unlike some watches seem to be. The sleep tracker on it seems to be so accurate and gives you really good details. The app is amazing too, everything is synced with my app on my phone and can read into further detail when I want to. Fitbit also has other apps that it can work with, like MapMyRun. If you found this review helpful, please let me know my selecting helpful at the bottom.
