## Description

Review editable sleep estimates from app inactivity, refine them with optional Apple Health and Watch evidence, and keep your data on device.

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.
