    It is recommended to take 10,000 steps a day but I had no idea how many steps I was taking. This fit tracker is an awesome tool for anyone who is health conscious.

    *Easy to set up and use
    *accurate step counter and heart rate monitor
    *Ability to time specific activities and get a summary of calories burned, steps, distance, average heart rate, etc
    *App stores data so I can see progress over time
    *Feels comfortable on my wrist
    *Tracks sleep: deep sleep, light sleep, and awake time
    *Tracker will vibrate and remind me to move if I’ve been sitting too long.
    *A fun way to keep track of daily activity.

    Suggestions for use:
    *I had a hard time trying to sync my phone to the fit tracker the first time. The directions offer good suggestions on how to sync the phone if it doesn’t happen automatically, and then it synced.
    *In the beginning the app seemed to have a few bugs but I haven’t had any more problems with it.

    Overall, I think this is a great product and I’ve enjoyed keeping track of my steps.

    This is about the 8th fitness tracker I’ve owned in the past 4 years, but it’s easily my favorite, and it was the cheapest.

    All told, this is a really solid little wearable for 40 bucks. It does everything well that is important to me:

    1. It Looks good
    2. It’s easy to keep using (convenient and easy to charge & charges fast – I charge it while I’m in the shower, so like 15 minutes every day or 2)
    3. It vibrates when I want it to (you can customize what notifications it should display, I get like 400 notifications a day, so I basically block out every noise my phone makes. I set this to only vibrate for texts & calls, so now my friends don’t think I’m ignoring them as often)

    I really really really love the charging situation. You don’t have to keep up with a random little cable, you can just plug it directly into any usb port. I hate keeping up with cables, and I’ve had a few smart watches with really weird finicky magnetic charges, etc. This is so much better, in my opinion, and USB ports are everywhere these days. I can literally charge my smart watch on the side of my TV, or my printer, or my Wireless router, lol. (I haven’t done this, but it’s cool that I could)

    Design / Style is also really cool. I love the way it looks (I got the Black) and fits on my wrist. I also really appreciate the attention to detail on this little guy. For example, the little loop that holds the extra length of the watch strap has a tiny little piece that fits into the holes on the watch strap. This keeps it in place, so it doesn’t slide back and forth. I don’t know why this hasn’t been a thing on every watch ever, maybe it has and I just haven’t had the right watches / trackers, but it’s pretty great.

    Now as far as the device itself, the screen and battery life are way better than they should be for $40. It seems to track everything as advertised (I do have a few complaints I’ll talk about below). All in all, the hardware is awesome at this price point.

    [This only applies to the android app] The software is where I was really impressed. Like I said, I’ve had a lot of fitness trackers from some major players, and also some non major players, and I assumed the weak link here would be the software (which is where all the magic happens). I was very pleasantly surprised – the software seems very well developed (I’ve written a few mobile apps). It’s responsive, attractive, nice animations, etc. It’s also extremely full featured – again, attention to detail. One of my favorite things is that you can set it to check your heart rate every so often automatically. I hadn’t had this option on any tracker before without downloading 3rd party apps. There are also all kinds of settings that let you do all kinds of stuff, but it can be kinda hard to find. Tap on settings, then on the device name at the top and you get a menu with all kinds of options. I did see another review that said the app is shared with another fitness tracker, so there’s that.

    The only negatives I’ve found are very specific to my current life situation, and probably don’t apply to many people, so I’m still giving it 5 stars. First – the steps are always way inflated for me, it took me a few days to figure out, but I think I know why. We just had twins a few weeks ago, so I’m doing a lot of burping & bouncing. I’m pretty sure this is being counted as taking steps, since it’s a repeated movement that may trigger similar to walking. Also – due to not sleeping more than a few hours at a time, again, because of the twins, The sleep tracking doesn’t register all that often. It actually says in the software that it can only register sleep if it’s more than 3 consecutive hours… I’ve only slept 3 consecutive hours 3 times in 2 weeks, so that’s not really the software’s fault. I’m hoping it’ll be updated to be able to track smaller naps and stuff, but I haven’t seen a wearable yet that does that without you manually putting it into sleep mode.

    I haven’t had a chance to use the GPS functions yet, but will update this review once I do. Again, just had twins 4 weeks ago, so not much time to go for a jog.

    This is an awesome piece of hardware, and at a great price!

    Very waterproof, can be washed directly, swimming.

    I used to have a fitbit, but it broke almost immediately, and I didn’t feel like spending a lot of money on a new one to have it break again. So, I started looking around and found this one. I was a bit skeptical when I saw the price, but to my surprise, it’s been working fantastically! It also arrived really quickly, which is good, since I’m starting to train consistently again.

    Love this smart watch sooo much! It is beautiful and smart at the price of a regular digital watch. It has so many functions, some of the function can only turn on when you sync your watch with your phone using the app that goes with this watch which is h band, a very common app for Chinese Fitbit. And it is still very waterproof and has no problem with swimming. Can also record the number of steps, Gave me a lot of help!

    My first impression of the DoSmarter Fitness tracker as I put it on my wrist, was that it was smooth and streamlined. You would not even notice that at its thickest point, it is 11 mm thick. Compared to my $200 Seiko watch this tracker is very light. After two weeks of normal usage I had expected tiny scratches on the plastic face plate. I could find none.
    I normally take a shower with my Seiko watch washing the metal band at the same time. Apparently all trackers in the same price range warns you not to take hot shower with it despite it being somewhat water-proof. So, I take it off before showering and wash the band separately. It is OK to run in the rain with it, which is very common here in the Pacific North West.
    Setting up to monitor steps (sport), sleep, heart rate (HR), blood pressure (BP), is easy using the Module Manager of the downloaded app on the cell phone. Tracking my BP takes a little effort as it does not always keep the setting.
    It offers a great tool to view the path I normally take for jogging. It requires you to activate bluetooth on the cellphone, which has a short range. So, you have to take the phone with you as you run (this is to be expected from trackers at this price range). At the end of the run you should be able to review your speed, pace and calories, distance completed, time completed and the path you have taken on a map. I am still tweaking some settings to see the map instead of just the path taken. This may be related to my cell phone, an Honor View10, and may not appear with other Android phones. I will update this once I have tried on a different phone.
    Update 12 Jan. 2020: After upgrading H-Band to the latest version, when you are ready to run, it asks you which map you want to use, as per attached. Since it is snowing, I am not going to run outside. I am satisfied that this works on my cell phone.
    Considering its price, the DoSmarter Fitness tracker provides all one would need of a tracker. The main feature why I bought this unit is its ability to analyze my sleeping pattern: how many hours I have a deep sleep and how many a light sleep, how long I sleep, what my sleep quality is, and – you decide – if you have sleep disorder. The rest the tracker has to offer is gravy. There is an array of prices for trackers that offer more options that you may be nice but you will never use. For the price this unit has given me all I need. I am happy with my choice of fitness tracker. I give this 5 stars.

    Update: as per Consumer Report chose your health tracker based on what you need and not what is available on the market that you will never use. It saves you money by trimming down to the basic units. A comment, battery life depends on the options. I got 5 days out of a charge with sleep monitoring plus the sport, heart rate and blood pressure. Without sleep monitoring I suspect you are fine with 7 days per charge.
