Sleep Detector notices how long the app has been away. When you return after a long interval, it creates an editable sleep estimate for review. App-away time alone is not treated as proof of sleep: low-confidence estimates always wait for your confirmation. For more context, optionally connect Apple Health and the Apple Watch companion. Sleep stages and selected recovery signals can refine a candidate; only periods you confirm are written back to Health when sync is enabled. REVIEW BEFORE SAVING • Inspect estimated start and end times • See confidence and evidence details • Edit, confirm, or dismiss each estimate • Review history, trends, and daily wellness context APPLE WATCH + HEALTH • View last night's duration and stages on your wrist • Refresh on demand—no continuous sensor workout • Read Health data only after permission • Write only confirmed sleep periods • Avoid duplicate Health entries PRIVATE BY DESIGN • No account • No advertising or tracking • No cloud sleep profile • On-device storage and analysis • User-initiated JSON and CSV export BATTERY CONSCIOUS Sleep Detector records lightweight app lifecycle timestamps instead of running a continuous background sensor session. iOS may suspend apps; the estimate is completed when Sleep Detector is reopened. Sleep Detector supports awareness and journaling. It is not a medical device and does not diagnose sleep disorders. Results depend on available evidence and user confirmation. ## Auto Sleep Detector & Tracker Screenshots - [Screenshot 1](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/f0/2a/b2/f02ab238-8a72-aeab-109b-b214cfd9b1cf/01-wake-up-with-clarity.png/1320x2868.png) - [Screenshot 2](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/85/6f/64/856f6418-dac0-26ce-ea26-b1dd8e383275/02-review-before-you-save.png/1320x2868.png) - [Screenshot 3](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource221/v4/28/fd/89/28fd895a-6886-dd5f-0bec-bd53f7faf1a5/03-apple-health-your-choice.png/1320x2868.png) - [Screenshot 4](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/ca/2c/c6/ca2cc6b1-071f-3c7f-7c38-19f726f2028f/04-see-patterns-not-guesses.png/1320x2868.png) - [Screenshot 5](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource221/v4/73/c1/16/73c11621-8ecb-9e6e-cd5a-927ed9dbe0e6/05-smarter-data-lighter-battery.png/1320x2868.png) ## Auto Sleep Detector & Tracker Rating Breakdown in United States - 5 stars: 0 (0%) - 4 stars: 0 (0%) - 3 stars: 0 (0%) - 2 stars: 0 (0%) - 1 stars: 1 (100%) ## Auto Sleep Detector & Tracker Available In - [United States](https://apptail.io/app/auto-sleep-detector-tracker-dUVv/united-states) - [Azerbaijan](https://apptail.io/app/auto-sleep-detector-tracker-dUVv/azerbaijan) - [Bulgaria](https://apptail.io/app/auto-sleep-detector-tracker-dUVv/bulgaria) - [Bahrain](https://apptail.io/app/auto-sleep-detector-tracker-dUVv/bahrain) - [Belize](https://apptail.io/app/auto-sleep-detector-tracker-dUVv/belize) - [Canada](https://apptail.io/app/auto-sleep-detector-tracker-dUVv/canada) - [China](https://apptail.io/app/auto-sleep-detector-tracker-dUVv/china) - [Colombia](https://apptail.io/app/auto-sleep-detector-tracker-dUVv/colombia) - [Germany](https://apptail.io/app/auto-sleep-detector-tracker-dUVv/germany) - [Estonia](https://apptail.io/app/auto-sleep-detector-tracker-dUVv/estonia) - [United Kingdom](https://apptail.io/app/auto-sleep-detector-tracker-dUVv/united-kingdom) - [Grenada](https://apptail.io/app/auto-sleep-detector-tracker-dUVv/grenada) - [Ghana](https://apptail.io/app/auto-sleep-detector-tracker-dUVv/ghana) - [Hong Kong SAR China](https://apptail.io/app/auto-sleep-detector-tracker-dUVv/hong-kong) - [Indonesia](https://apptail.io/app/auto-sleep-detector-tracker-dUVv/indonesia) - [Iceland](https://apptail.io/app/auto-sleep-detector-tracker-dUVv/iceland) - [Jamaica](https://apptail.io/app/auto-sleep-detector-tracker-dUVv/jamaica) - [Jordan](https://apptail.io/app/auto-sleep-detector-tracker-dUVv/jordan) - [South Korea](https://apptail.io/app/auto-sleep-detector-tracker-dUVv/south-korea) - [Sri Lanka](https://apptail.io/app/auto-sleep-detector-tracker-dUVv/sri-lanka) - [Lithuania](https://apptail.io/app/auto-sleep-detector-tracker-dUVv/lithuania) - [Luxembourg](https://apptail.io/app/auto-sleep-detector-tracker-dUVv/luxembourg) - [Latvia](https://apptail.io/app/auto-sleep-detector-tracker-dUVv/latvia) - [Mali](https://apptail.io/app/auto-sleep-detector-tracker-dUVv/mali) - [Macao SAR China](https://apptail.io/app/auto-sleep-detector-tracker-dUVv/macau) - [Malta](https://apptail.io/app/auto-sleep-detector-tracker-dUVv/malta) - [Namibia](https://apptail.io/app/auto-sleep-detector-tracker-dUVv/namibia) - [Nigeria](https://apptail.io/app/auto-sleep-detector-tracker-dUVv/nigeria) - [Nepal](https://apptail.io/app/auto-sleep-detector-tracker-dUVv/nepal) - [New Zealand](https://apptail.io/app/auto-sleep-detector-tracker-dUVv/new-zealand) - [Qatar](https://apptail.io/app/auto-sleep-detector-tracker-dUVv/qatar) - [Romania](https://apptail.io/app/auto-sleep-detector-tracker-dUVv/romania) - [Slovenia](https://apptail.io/app/auto-sleep-detector-tracker-dUVv/slovenia) - [Slovakia](https://apptail.io/app/auto-sleep-detector-tracker-dUVv/slovakia) - [Senegal](https://apptail.io/app/auto-sleep-detector-tracker-dUVv/senegal) - [Uganda](https://apptail.io/app/auto-sleep-detector-tracker-dUVv/uganda) - [Angola](https://apptail.io/app/auto-sleep-detector-tracker-dUVv/angola) - [Vietnam](https://apptail.io/app/auto-sleep-detector-tracker-dUVv/vietnam) --- ## About AppTail [AppTail](https://apptail.io) is a mobile app intelligence platform providing app analytics, ASO (App Store Optimization) tools, keyword tracking, competitor analysis, revenue estimates, and review monitoring for iOS App Store apps.
