The bracelet was used with a Huawei phone with the Huawei Health app. I really liked the "smart alarm clock" function - the bracelet tries to wake you up in the correct phase of sleep. It seems to work (it's easier to get up). But the main thing is that you wake up from the vibration on your wrist, and not from the sound. If you need very accurate indicators of steps, distance traveled, then you should take bracelets with GPS.
