Place the iPhone face-down on the bed; the mic listens for breathing and movement patterns that correlate with light vs deep sleep. No accelerometer-on-the-mattress trick.
Set your latest wake time (e.g. 7:00 AM). The alarm picks the lightest sleep moment in the 30 minutes before — so you wake during light sleep, not yanked out of deep.
After-night graph shows estimated time in light sleep, deep sleep, and awake periods. Stored in HealthKit alongside Apple Watch sleep data.
Optional: record audio events during the night. Useful for documenting snoring or sleep talking to discuss with a doctor. Recordings are local; you delete them anytime.
Sleep Cycle ($40/yr) and Pillow ($30/yr) push expensive subscriptions for what is fundamentally a microphone + algorithm. $19.99 lifetime here covers it forever.
No login, no cloud sync requirement. All processing on-device. Verify by Airplane Mode.
Swarmval apps avoid surprise weekly pricing. The upgrade path is visible before purchase and support links are easy to find.

Sleep Cycle Alarm is planned around local-first handling for files and app data. Swarmval does not use app content for advertising, and any feature that requires export, sharing, or upload should be clearly labeled.
Read privacy policyIt is reasonably accurate at detecting awake-vs-asleep transitions and at distinguishing light vs deep sleep based on movement and breathing patterns. It is not a sleep-lab polysomnography substitute. For medical sleep disorders, consult a doctor.
Plug in overnight — the app expects this. Battery drain is low (the processing is light), but typical use is on the charger.
Yes, sleep stage estimates are written to HealthKit so they appear in the Apple Health app alongside any Apple Watch sleep data.
Sleep Cycle is $40/year forever and ad-supports its free tier. Sleep Cycle Alarm by Swarmval is $19.99 lifetime, no ads, no subscription, no upsells.
Same kind of work. Same anti-fleeceware promise.
