Your Phone Is Your Sleep Tracker
PhoneSense uses built-in iPhone and Android sensors to detect sleep stages passively. No wearable. No manual entry.
How PhoneSense Works
1
Motion Detection
CoreMotion (iOS) / accelerometer (Android) samples at 10 Hz to detect movement patterns.
2
Acoustic Analysis
Microphone captures ambient audio features (breathing rhythm, room changes) — no raw audio stored.
3
On-Device Classification
Every 30 seconds, sensor fusion classifies your current stage: Awake, Light, Deep, or REM.
4
Live Stage Display
See your current sleep stage on the Dynamic Island (iOS) or Lock Screen — updated in real time.

See Your Sleep Stage in Real Time
iPhone users can see their current sleep stage on the Dynamic Island and Lock Screen — updated every 30 seconds. Android users see a persistent Lock Screen notification with the same live data.
