We record the sounds while you sleep and show you when snoring got loud, hour by hour. A single total tells you almost nothing. Forty-two snoring events last night is a number. Knowing it was concentrated between two and three in the morning is something you can act on, because you can think back to what you did that evening and how you were lying. Hour by hour The night is recorded minute by minute and drawn as a chart. Quiet stretches and loud ones are visible at a glance, and you can zoom into a single hour to look closer. Hear the moment We keep short clips around the moments that were detected. Pick a time from the list and listen to what actually happened. To count quiet snoring too, the whole night is also recorded while measuring and analyzed again on your phone in the morning. That recording takes about 100 MB for 8 hours, and only the last 3 nights are kept. Set clip storage to “Don't save” and nothing is recorded. No single signal decides on its own The app spends five minutes learning your room's background noise, then only considers sounds that rise above it. Candidates are filtered again by sound classification, breathing periodicity, and how far they rise above the background. Snoring repeats in time with your breath, while a closing door or a passing car is a one-off. Stretches where speech is detected are held back, because if you are talking you are awake. When the air conditioner comes on at three in the morning, the baseline follows it. That is why we do not use a fixed threshold. At night, the screen gets out of the way The measuring screen has no live graph, no running count, and no animation. In a dark room, anything that moves repeatedly keeps you awake. After five seconds the screen dims itself, leaving only the time, large enough to read if you wake up. Recordings never leave this device Recording and analysis both happen on your phone. Audio is never uploaded, and no account is required. Clips are excluded from iCloud backup and deleted automatically once your retention period passes. You can erase everything from Settings at any time. What is free Measuring, reports, and the hour-by-hour chart are all free. We never lock data you have already recorded. The free tier covers three nights a week and shows seven days of trends. Every clip is still saved; free plays the first 30 of each night. Pro is a one-time purchase, not a subscription. It removes the nightly limit, plays every clip you have recorded — including the ones from before you upgraded — extends trends to 90 days, unlocks CSV export, and removes ads. Family Sharing works too. If someone sleeps beside you The microphone cannot tell two people apart. Sounds and conversations from anyone in the room may be recorded. Please let them know beforehand. This app is not a medical device and cannot be used to diagnose or treat any condition. ## Pricing and in-app purchases Base price: Free. **One-time purchases** | Purchase | Price | Type | | --- | --- | --- | | SleepSound Pro | $4.99 | one-time | ## Is SleepSound Tracker safe?
