NightProof: Snore Recorder

NightProof records and labels nighttime sounds — snoring, dog barking, or any noise that breaks your sleep. Everything stays on your phone. No cloud, no ads, no analytics, no account.

Pick a profile, place the phone next to your bed, hit Start. NightProof listens in the background and saves a clip every time the noise crosses your detection threshold (with a pre-roll buffer so you also catch the moment before).

Wake up to a sleep score, a timeline of every event — timestamp, duration, peak dB, AI-classified label (snoring, dog, traffic, rain, silence...) — and possible apnea hints (snore → silence ≥10s → loud gasp).

Why people love it
- Sleep score for every night, with multi-night statistics
