Snorebook: Snore Recorder

Snorebook is a sleep sound recorder. Leave your phone by the bed and it keeps only the moments that matter — snoring and sleep talk — so in the morning you can hear what happened last night in a few minutes.

■ Made for you if
• Your partner says you snore and you want to hear it yourself
• You talk in your sleep and wonder what you say
• You want to see whether drinking, late nights or a rough day make your snoring worse
• You want your recordings to stay on your phone, not on someone's server

■ 1. Records sounds, not silence
The microphone listens all night, but quiet stretches are never saved. Snorebook learns the usual noise level of your room and keeps a short clip — including the 2 seconds before — only when a sound stands out. An on-device sound model sorts each clip into snoring, sleep talk or other sounds. No internet connection needed.

■ 2. Set up the night on one screen
• Delay before detection: now, 5, 10, 15 or 30 minutes — skip the tossing and turning before you fall asleep
• Three sensitivity levels: low, normal, high
• Choose which sounds to keep, for example snoring only
• A 5-second mic test, charging status and battery-saver advice before you start
• One tap on the home screen gets you ready with last night's settings

■ 3. Keeps recording all night
Recording continues from the notification bar with the screen off or while you use other apps. Pause for a trip to the bathroom and resume; several recordings in one night are grouped as one night. Naps are kept separately. After a while the screen dims to a clock only.

■ 4. Morning report
• Snore ratio, the change from the previous night and the hours with the most snoring
• Snoring minutes, sleep talk count, other sound count
• A night-long sound timeline and stacked bars by hour and kind
• Loudness ranges (quiet, normal, loud)
• Memo tags (drank alcohol, had coffee, slept late, felt unwell and more) and a 1–5 morning freshness score
• Swipe between nights; merge with the previous record, split, or mark as a nap

■ 5. Clip player
Listen with a waveform, jump 10 seconds back or forward, and fix the kind if the model got it wrong. Star the clips that matter, share them as a file or delete them. The clip list filters by kind and sorts by time or loudness.

■ 6. History and trends
• Week, month, 3-month and all-time calendars with each night's snore ratio
• Snore ratio and morning freshness trend chart
• Tag comparison, for example nights with alcohol versus nights without
• Averages by day of the week

■ 7. Light and private
• Recordings and records stay on your phone and are never uploaded automatically
• Keep period and storage cleanup to control space
• Export and import a backup file to move to a new phone
• Bedtime reminder with one more nudge 30 minutes later
• Dark and light themes, English and Korean
