ZeRound3 records the hours of sleep and the quality of your sleep (light sleep, deep sleep, wake up).
Open the MyKronoz app> Go to Settings menu> Advanced settings> Click Sleep to set the desired bedtime and wake time. By default, ZeRound3 will follow your sleep from 23h to 7h.
You can also view your last recorded data directly from your ZeRound3.
Go to the Sleep menu of your watch> Tap the start icon to activate sleep tracking> Tap the Stop icon to stop tracking.
