Capture quietly
Start once, lock your iPhone, and let Sleep Recorder listen for noteworthy sound moments overnight.
SleepMemo · A private overnight sound diary
Wake up
to the story
of your night.
Keep the small moments worth hearing. Let the long hours of silence disappear.
On-device only
Made for quiet curiosity, not judgment.
No cloud audio. No ads. No tracking.
Keep the moments
Review short clips around detected moments instead of searching through hours of silence.
Stay private
Audio, notes, labels, and patterns remain on your device. There is no account, tracking, or developer cloud.
Clear by design
Personal insight.
Never a diagnosis.
Sleep Recorder can suggest familiar sound types such as snoring, coughing, speech, and environmental noise. Suggestions can be wrong and are always yours to review. The app does not measure sleep quality or diagnose any health condition.
