An iPhone app that records short, noteworthy overnight sound moments instead of storing hours of silence.

Landing page captured for the 2026-08-28 issue.

Field notes

SleepMemo’s workflow begins with an overnight listening session on a locked iPhone, then presents short clips around detected sounds for morning review. The page names snoring, coughing, speech, and environmental noise as possible categories, while warning that suggestions can be wrong. It also draws a firm boundary around the product: the app says it does not measure sleep quality or diagnose conditions, and keeps audio, notes, labels, and patterns on the device.
