Alarm rings before set alarm time

  • Smart alarm is enabled (see Smart wake up), so the app is waking you within the smart period, when light sleep is estimated.

  • If that is not what you expect, disable smart period in Settings → Alarms → Smart wakeup → Smart period for all your alarms, or for one alarm in alarm → Smart period.

  • You can also try different smart period: shortest period is 5 minutes, longest is 2 hours.
