Someone tells you that you snore, or that you talk in your sleep, and you have no way to check. Setting your phone to record all night works, technically, but then you’re stuck scrubbing through eight hours of silence to find the ten seconds that matter. I built Snorebook to skip that part.
I wanted something that sat on the nightstand, listened all night, and handed me back only the moments worth hearing in the morning. Everything else — the room’s normal background noise, the long stretches of nothing — gets thrown away automatically. No cloud account, no uploading audio anywhere, just a clip list and a report when you wake up.
What it does
- Learns your room’s normal noise level overnight and saves a clip, including the two seconds before, only when something stands out — an on-device sound model then sorts each clip into snoring, sleep talk, or other, all without an internet connection
- Lets you set a detection delay (now, 5, 10, 15, or 30 minutes) so it skips the tossing and turning before you actually fall asleep, plus three sensitivity levels and a filter for which sound types to keep
- Keeps recording in the background with the screen off, groups multiple sessions from one night together, and dims to a plain clock display after a while
- Builds a morning report with your snore ratio, how it changed from the night before, a timeline of the whole night, and a clip player with a waveform, 10-second skip, and the ability to relabel or star clips
- Tracks trends over weeks and months, lets you compare nights by tag (alcohol, coffee, late nights), and keeps every recording on your phone with export/import for backups
The setup screen is one page: pick your delay, sensitivity, and which sounds to keep, run a quick mic test, check your battery settings, and tap once on the home screen the next time using last night’s settings. The morning side is built the same way — a snore ratio, a freshness score you rate yourself, and a night-long timeline instead of a raw audio file you’d never actually sit through.
This is for anyone who’s been told they snore or talk in their sleep and wants to actually hear it instead of taking someone else’s word for it. It’s also useful if you’re curious whether alcohol, late nights, or a stressful day change how much you snore — the tag comparisons make that visible over time. If keeping personal recordings off someone else’s server matters to you, that’s built in by default, not an upsell.
Snorebook shows ads, and a single Remove Ads purchase turns them off — no subscription. It’s not a medical device and won’t diagnose sleep apnea or anything else; if you’re genuinely worried about your sleep, talk to a doctor. If you just want to know what happened last night, put your phone by the bed tonight and check Snorebook on Android tomorrow morning.
