4 stars: It works with my M2S bracelet. It shows the data of the watch, there is no Problem, but don't try the APP in german language. The worst translation I habe ever seen... In my opinion a good APP with a good watch. Remember: it's for a Smart Watch for 20$, not a Garmin or a Samsung!!! ;-)
3 stars: App shows all data from my bracelet... when it works... Constant BT disconnects and fail to reconnect. App have some bug on bluetooth and after connection fail some times hang phone untill full restart ( CPU load 100% and phone start to heat up). Unhappy. Edit... last updates make connection more stable. Bracelet now reconnects after connection loss.
4 stars: Seems to work so far. I don't know how accurate, and it took a while to get it connected and working but it works.
3 stars: App works ok with my M2S but weather does not update and will not change to C to F. There are no settings in the app for the weather or any instuctions of how to set up the weather for the watch. How can I get the weather working correctly on the watch?
3 stars: This app notifications is worse than the other wearfit app.. The other one offers more options and does not vibrate and tell me what I sent as a txt to someone..So annoying.. Everything else works ok.. So I'm using the original app cuz of that..I couldn't figure out how to stop it from telling me my text messages that I send out without turning off the messages option which defeats the purpose of having text notification on...
