How many times did I move or wake up during sleep?

I wouldn't say the band tells the exact how much times you wake up during sleep, because for most these bands, the "awake-determine" mechanism is more based on movement detection than other more accurate data(brain activity, muscle activity, ect.). But in general, the all those bands/trackers provide good indication of your sleep quality. Just don't expect it to be a very precise tool to measure your sleep.
