The watch and app are alright, when they work. On multiple occasions the watch will not be able to connect to my phone and is unable to connect to the app for tracking any metrics. The app will ask to retry connecting to the watch, and the watch thinks it's still paired with the phone, even after turning off Bluetooth and wifi. The app takes a minimum of a minute to sync to the watch (other brands take less then 5 seconds). Metrics are basic and not that accurate. Fitbit has a much better app.
