NightReplay: Sleep Recorder

Wonder what happened overnight? Replay short sound clips, check possible snoring or sleep talk, and turn your recordings into one small change with optional AI guidance.

Wonder whether you snored or talked in your sleep? Hear the moments for yourself.

NightReplay turns detected nighttime sounds into short clips you can replay the next morning. Check what was captured, correct a mistaken label, and use optional AI guidance to decide what to try next.

HEAR THE MOMENT, NOT HOURS OF AUDIO Start recording before bed. NightReplay detects possible snoring, speech, coughing and other sounds, saving short event clips on your iPhone instead of an entire night of raw audio. Focused replays last up to 10 seconds, so you can get straight to the sound.

CHECK BEFORE YOU DRAW CONCLUSIONS Replay, pause, seek or loop a clip. Filter sound types, bookmark moments you want to keep, and correct labels or exclude detections from your analysis. In a shared room, recordings cannot tell you who made a sound.

MAKE ONE CHANGE AND OBSERVE Choose a small bedtime habit to try, mark the days you followed it, and compare suitable recordings over time. Weekly summaries bring together captured time, detected events and how you felt in the morning. Comparisons describe patterns, not proof that a habit caused a change.

GET AI GUIDANCE WITH CONTEXT With your permission, AI summaries and the coach use your recording metrics and selected event details to explain observations and suggest a practical next step. Guidance includes supporting sleep-education sources. Saved summaries remain available without generating a new response every time you open the page.

CHECK YOUR SETUP BEFORE BED Use a 10-second microphone trial with a countdown and playback progress. Add room context, play relaxing sounds and start your recording. Capture gaps are shown so an incomplete recording is not mistaken for a quiet night.

KEEP CONTROL OF YOUR RECORDINGS Audio clips stay on your iPhone unless you explicitly share them. Optional AI sends disclosed structured data and your questions to our server and DeepSeek, not audio files or clip transcripts. You can decline or revoke AI permission and continue recording and replaying.

NightReplay is a general-wellness tool, not a medical device. Sound detections may be incorrect. Recording time is not measured sleep time, and the app does not determine sleep stages or diagnose sleep apnea. For ongoing snoring, breathing or sleep concerns, consult a qualified healthcare professional.
