Wakes you during light sleep within a chosen window — feels gentler than a regular alarm.
1. Wake window opens — N minutes before your set time, Mumbly starts looking for signs of light sleep.
2. Light sleep detected — alarm rings + vibrates to wake you gently.
3. No detection by wake time? — alarm fires at your set time anyway, so you never oversleep.
Smart Alarm needs recording active overnight — the detection runs in the recording service, so it works even with the screen off.
