Drowse: Sleep Quality Tracker

Record your night, listen to detected sounds, and check the evidence behind your statistics. Drowse keeps original detections, reversible corrections, and measurement gaps separate on your iPhone. ■ Review your record • See original automatic detections and the groups remaining after your corrections • Listen, seek within a clip, mark a false detection as not snoring, and undo your changes • Distinguish missing recording from recorded audio that was not analyzed • Compare lifestyle tags with excluded records and reasons shown; unanswered tags are not counted as absent ■ Analyzed only on your device Recording, sound analysis and storage all happen on your iPhone. Nothing is sent to a server, and there are no ads or trackers. ■ Wake-up alarm • Smart alarm (experimental): wakes you a little early when you stir within your wake-up window, and always rings at the final time • Fixed alarm, or sleep analysis with no alarm • Six alarm sounds made in the app, like Dawn Bells, Music Box and Morning Harp, with snooze • On iOS 26 it rings like a system alarm, even in Silent mode ■ Sleep sounds • Rain, waves, breeze, summer night forest and pink/brown noise generated live on the device • Sleep timer with a gentle fade-out ■ Morning journal • Sleep quality score from sleep time, efficiency, time to fall asleep, time awake and regularity, with every part of the calculation shown • Time in bed and time asleep, sleep stage chart (with Apple Watch data) • Snoring timeline with sample sounds; mark misdetections as "Not Snoring" • Overnight heart rate and wrist temperature (read-only from Health) • Morning mood, sleep notes and lifestyle tags • Chat with an on-device AI sleep assistant (iOS 26, Apple Intelligence devices) ■ Statistics • Sleep quality, regularity, sleep time, bedtime and snoring by day, week, month and all time • Weekly reports and lifestyle tag comparisons ■ Honest records • Time that couldn't be analyzed is shown as a gap, not as 0% • Phone-only sleep estimates and the smart alarm are labeled experimental Drowse is for logging sleep and snoring sounds and observing changes. It does not diagnose conditions such as sleep apnea or judge treatment effects. If you have concerning symptoms, talk to a medical professional. The microphone is used while recording, so keeping your phone plugged in is recommended.
