ZeTrack+ records the hours of sleep and the quality of your sleep (light sleep, deep sleep, wake up).
Pre-defined sleep
Open the MyKronoz app> Go to Settings menu> Advanced settings> Click Sleep to set the desired bedtime and wake time. By default, ZeTrack+ will follow your sleep from 23h (11pm) to 7h (7am).
You can also view your last recorded data directly from your ZeTrack.
