Don’t want to wear a smartwatch to bed? When Did I Sleep uses motion and activity patterns from your iPhone, along with gaps in device use, to estimate when you fell asleep and woke up. No Apple Watch or additional wearable is required. There is no need to start tracking manually every night. Simply use your iPhone as usual, then check the app the next day to see your estimated bedtime and wake time. KEY FEATURES • Estimate your daily bedtime and wake time • View recent routine records • Review late nights, early mornings, and changes in your routine • Check your latest result with Home Screen widgets • Sync your data across your devices with iCloud WHO IS IT FOR? • People who do not own an Apple Watch or other smartwatch • People who do not like wearing a watch while sleeping • Anyone who simply wants to understand their daily routine • People who want to keep track of late nights and wake-up times • Anyone who does not need detailed sleep-stage analysis PRIVACY Motion and activity information is used only to generate estimates of your routine. It is not used for advertising or cross-app tracking. PLEASE NOTE This app provides estimates based on device activity and usage patterns. It is not a medical-grade sleep monitoring tool. Results may differ from your actual sleep time if your phone is not nearby, the required permissions are disabled, the phone remains unused for an extended period, or audio or video continues playing before you fall asleep. This app does not detect deep sleep, light sleep, or REM sleep. It is not intended to diagnose or treat medical conditions or replace professional medical advice.
