Auto Sleep Detector & Tracker vs Cycle Cipher

Understand when you may have slept—even if you forgot to start a timer. 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.
