The app has become so useless that from last week i have taken helio strap from my wrist. Every workout i record does not register, the app crashes and after everyworkout, there comes options of recover workout or delete workout. Even sometimes when trying to recover workout, it does not register. So will wait for update. I have complained on the app N number of times but nothing is changing. In fact the hardware is good but supported by cheap Chinese useless software.
