LONGET Fitness Tracker，Activity Tracker with Heart Rate Monitor Waterproof Smart Fitness Band with Step Counter,Calorie Counter，Smart Watch for Android and iOS Smartphone

Honestly, I amazed at the 5 star reviews here... The product works. Kinda. Counts steps... and shows something what might be your pulse...The software with it is crap.It needs access to everything your phone has, contacts, pictures, allow it to dial numbers, etc. I refused those.You don't have a "create account and log in" option, you HAVE to use some social media to log in. Since I don't want to autopost to the world, how am I sleeping, I created a fake twitter account for it to be able to log in.Still, I can't start any exercise session as "You have to log in". Ok log in - "You are already logged in"...If you EVER stop the app, or EVER go out of the range of your phone, it stops registering historical information. It does NOT start again when you are in range or start the app again. Only if you reset the bracelet AND the app.Loosing ALL previous history data in the process.It works in water, however the activity level it counts for swimming is WAAY low... Like walking next to the pool low... Touch screen have issues when wet....In summary, you could get a an old fashioned simple step counter instead of this. All the extra functionalities this offers in addition to the simple step counter are essentially useless due to some bugs.Update. Today it stopped counting the steps mid day, and restarted only after reset. So it ix unreliable even as a simple step counter. Changed my rating to 1. Completly useless piece of garbage.

The description says that the watch is IP68 but I just took a shower while I was wearing it and after that I noticed humidity inside the watch as you can see in the picture. It says that you can receive notifications from Messenger but it is a lie, you only can recive notifications from an small list of known apps, you can receive notifications from facebook app but only birthdays and comments but the watch doesnt alert you when new messages arrive. Im am very dissapointd because I was searching for a watch I could wear while swimming*Pros: the battery last almost a week, you can set up alarms.

Fitness tracker keeps track of your steps, sleep,heart rate, the distance traveled, I can not verify the accuracy as the treadmill gives me a distance traveled that does not match the tracker, which is fine because I only use it as an estimate. The APP that it uses is total crap, it constantly cuts off and will not reconnect, the instructions are in Engrish, check the reviews for it before buying. WEARFIT2.0 is the name of the APP. could not recommend anything else on this price range as I haven't tried anything else.

Well, it read my heart rate, though, often does not work as intended.- wanted to lead HR continuously with LCD on all the time, but display disappeared in a few seconds after touch on the screen.- Apps often give up showing real time date even though watch & phone are paired via bluetooth all the time.- Sometimes the watch shows totally different time. probably Chinese time?- the display started to become bright during night time that bothered my sleep.- setting change via apps not reflected to the watch.- It displays something not written on the instruction.- had to reset to factory shipped condition several time within 24 hours from the delivery since the watch seemed to be malfunctioning.Giving 2 stars as it seems to work occasionally, but not that reliable.

This is a great product. I've been using it for 2 weeks and I love that it tracks my steps & tells me what time it is!Sync to app on your phone to show how many steps/miles you've walked, calories burned. I can't seem to get it to show my sleep pattern but everything else works great. Easy to charge in any USB Port also.Its much cheaper and reliable alternative for FITBIT.

I bought this to get a more accurate read of my calories burned throughout the day, and track my steps without using an app that drains my phone battery.The instructions were very basic and didn't cover half the functions. Both the instructions and the app used such broken English that it's difficult to understand what little they do explain. The tracker syncs with the app erratically. Sometimes it syncs just the heart rate or steps, or sometimes nothing at all.To top it off, the tracker itself is very inaccurate. The device moving on my wrist changes my heart rate reading. And the pedometer seems to log my steps randomly. Not counting my steps walking through the house, but crediting me for steps while I'm driving, for example.Overall, this thing is next to useless. I may as well keep guestimating my health stats throughout the day.

The tracker is cheap enough and it does some of what it claims but it won’t keep up with blood pressure and it is constantly changing time zones and going from analog face to digital face without being touched. Basically not even worth the low price

it works for heart rate monitor sort of. Readings vary a lot. But worst problem is they only stay for seconds. No way to keep them on continously or even more than a few seconds. You have to tap it carefully to get a reading. Not usable for me.
