About this app
Hear the moments that shaped your night. NightReplay is a private sleep sound recorder for people who want to understand the sounds and patterns around their sleep. Start a recording before bed, then review a clear morning summary and replay the short sound clips that matter. RECORD AND REPLAY KEY MOMENTS NightReplay detects notable sound events such as snoring, sleep talk, coughing, and environmental noise. It does not keep an entire night of raw audio. Only short clips around detected events are saved locally on your iPhone, where you can replay or delete them. UNDERSTAND YOUR NIGHT Review your recording duration, quiet periods, detected events, timeline, and recent consistency. Add a quick morning mood and habit check-in to give your reports more context. NightReplay reports only what it measures and does not claim to detect medical conditions or sleep stages. OPTIONAL AI SLEEP GUIDANCE After you give permission, NightReplay can use your structured sleep metrics and your question to prepare a morning brief or answer questions about recent patterns. Raw audio and clip transcripts are never sent to the AI service. Where relevant, suggestions include links to general sleep education from organizations such as the CDC, NIH/NHLBI, and the American Academy of Sleep Medicine.
