Sleep Stage Estimation
Infers sleep stages from sound patterns — silence indicates deep sleep, micro-movements indicate light sleep or REM.
Smart Alarm
Wakes you during your lightest sleep phase within a 30-minute window before your alarm, so you feel refreshed.
Wellness Integration
Sleep data automatically feeds into your Physical dimension's sleep driver, improving your overall VLC score.
