Don’t bother. Return the watch if you can. – WearHeart Review

This is the most useless thing ever. The watch works as a watch but don’t expect to get any useful health data. I haven’t worn it in a week yet it still seems to be reading and recording my heart rate. The BP will not calibrate with readings input from my manual cuff. The ECG is probably ok, but again no useful data. The translation from Chinese in the app is terrible. Neither app nor watch will sync with Apple health, even though the literature for both says it syncs to iPhone. VERY misleading. None of the other functions are anything better than a $10 digital watch. Save your money and just get a Fitbit or Apple Watch. This is a waste of time and money, Apple should just remove it from the App Store and be done with it.
