KEY FEATURES
- Apple Watch Companion
See last night's summary, browse past nights, and view live biometrics during a recording. Stop a recording from your wrist.
- Sleep Stages from Apple Watch & Wearables
Pull sleep stages, heart rate, HRV, respiratory rate, blood oxygen, and wrist temperature straight from your watch or any wearable that syncs to Apple Health.
- Audio Sleep Stage Estimation
Sleep stage classification from audio alone. Breathing regularity, breathing rate, movement, and snoring patterns combine to estimate Light, Deep, REM, and Awake.
- Hypnogram Source Picker
Switch the nightly sleep stage chart between audio analysis and Apple Watch data. Compare both views of the same night.
- Sleep Score Watch Complication
Add the Snore Timeline complication to any watch face for last night's sleep score at a glance.
- Snore Detection
Every snore captured with volume, duration, and frequency. Tap any snore to play it back.
- Snore Nudge
When sustained snoring is detected, your Apple Watch taps your wrist so you shift position, without waking you. Every nudge is saved to the nightly summary with how your snoring responded in the minutes around it. Requires a paired Apple Watch.
- Snores Per Minute
See your snore rate charted across the whole night against your personal baseline, with a breakdown of how snoring built up and settled around each time you woke.
- Visual Snore Timeline
See your entire night at a glance. Enable Loud Sound Detection for frequency-based coloring showing low, mid, and high frequencies.
- AirPods & Bluetooth Recording
Record through AirPods or a Bluetooth headset instead of the phone mic, with automatic level calibration for consistent volume.
- Sleep Talking Detection
Speech recognized as sleep talking and displayed on your timeline with playable clips.
- Breathing Pause Detection
Flags 10+ second silence followed by a recovery breath, a pattern that may explain poor sleep quality.
- Sleep Score & Insights
A nightly score based on duration, stage balance, efficiency, time to fall asleep, awakenings, and snoring.
- Sleep Factors
Tag what shaped your night, like caffeine, alcohol, or a late meal, and see which factors line up with better or worse sleep over time.
- Sleep Schedule & Wake-Up Alarm
Set a bedtime reminder and a wake-up time. Recording stops at your wake-up time with an optional alarm sound.
- Smart Wake Up Alarm
Wake during a light-sleep moment in a window before your set time, so you start the day less groggy. The alarm fades in from quiet, and still rings at your set time if a light-sleep window never comes.
- Wake by Wrist Tap
Wake to silent taps on your Apple Watch instead of a sound, so you can get up without disturbing a partner. Requires a paired Apple Watch.
- Loud Sound Detection
Capture any sound above a volume threshold. Useful for alarms, pets, or mumbling.
- Weekly Trends
Track progress week over week with charts comparing duration, scores, and efficiency.
- Custom Range Export
Pick a date range and choose what to include: nightly summaries, stages, episodes, biometrics, and audio. Generate CSV reports for sleep specialists.
- Completely Private
Everything on your device. No account required. Audio never leaves your phone.
