AutoSleep value

$5 one-time purchase. NO subscription. Genuinely better than Apple\'s built-in sleep tracking. Made by indie developer (David Walsh). Updated regularly. Apple Watch Series 4+ supported. iPhone-friendly UI.

Detailed sleep stages

AutoSleep separates sleep into: Awake, Light, REM, Deep with more granularity than Apple\'s 4-stage model. Heart rate variability + motion data combined. Better correlation with polysomnography (clinical sleep studies).

Sleep debt tracking

AutoSleep calculates rolling sleep debt — how much sleep you\'re owed based on goal vs actual. Cumulative over weeks/months. Insight into chronic under-sleeping. Apple Watch alone doesn\'t show this.

Smart alarm during light sleep

Set wake window (e.g., 6:00-6:30am). AutoSleep wakes you DURING light sleep phase — better wake feeling than rigid alarm. Apple Watch haptic alarm or iPhone alarm. Single best wake feature in any sleep app.

HRV recovery scoring

Apple Watch HRV during sleep. AutoSleep interprets: are you recovered today? Athletic users adjust training. Health-conscious see chronic stress patterns. Apple Health doesn\'t surface HRV like AutoSleep.

Apple Watch battery integration

AutoSleep aware of Apple Watch battery. Recommends charging schedule. Apple Watch Series 10 + AutoSleep + nightly MagSafe charge = sustainable workflow. Ultra 2 less battery management needed.

vs Apple\'s built-in sleep

Apple Sleep: simpler UI, basic stages, free, integrated. AutoSleep: more detail, sleep debt, smart alarm, HRV insights, $5 one-time. For users who want REAL sleep insight — AutoSleep dominates. For casual users — Apple\'s built-in sufficient.

Privacy + data

Local processing on Apple Watch + iPhone. Apple Health storage. NO cloud upload. Privacy-first. AutoSleep doesn\'t monetize data. Same privacy as Apple Health.
