Capture quietly
Start once, lock your iPhone, and let Sleep Recorder listen for noteworthy sound moments overnight.
SleepMemo · A private overnight sound diary
Sleep sound recorder.
A private diary.
Wake up to the story of your night. Keep the small moments worth hearing and let the long hours of silence disappear.
SleepMemo is awaiting App Store review for iPhone. Explore the guides while you wait; download availability will be linked here after release.
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.
Start with one useful night
The first completed night unlocks all its clips. After that, Free includes recording, the ten strongest clips per night, manual review and a seven-day diary.
More context with Premium
Premium adds all clips, longer retention, notes, context tags, deeper comparisons and private text summaries. Monthly, annual and Lifetime options are shown in the app.
Keep the recording yours
The temporary full-night file is deleted only after clip preparation succeeds. Audio is excluded from device backups. Save or delete nights deliberately.
Clear by design
Personal insight.
Never a diagnosis.
Apple’s on-device sound classifier can suggest broad sound types such as snoring, coughing, speech, and environmental noise. These are hints: a label is saved only when you choose it. Suggestions can be wrong. The app does not measure sleep quality or diagnose any health condition.
