The firmware needs to be improved. In particular, it is necessary to at least optionally add a complete screen off when activating workouts from a mobile phone. Some pros: Cool game. Pulse measures, counts steps, sleep controls. Equipped with small functions, even trying to wake up. With its cons: Of the little things - the alarm clock is stupid, even the application does not move the time under the sleep phases. Of the major problems - the screen lock in normal mode is purely nominal, in training mode there is not even such a nominal one AT ALL, as a result, your jacket can complete the workout for you at the most interesting place and generally untie the bracelet from the phone. The same nonsense happens even when activating the workout from the app.
