Sleep Debt reads your sleep data from Apple Health and shows you how much sleep you actually owe yourself, with a recommended bedtime to help you catch back up.
Sleep Debt needs sleep data in Apple Health to work. Open the Apple Health app and confirm there are sleep samples in the past 14 days. If you have an Apple Watch, make sure sleep tracking is enabled in the Watch app. The first night of data may take a few hours to appear in Health after waking up.
The algorithm uses a 14-day rolling window, so a single short night is averaged into your recent history. Bigger shifts in your bedtime recommendation typically reflect multi-night patterns, not one-off nights.
iOS Settings → Health → Data Access & Devices → Sleep Debt → turn off the categories you want to revoke.
The reminder is scheduled based on your goal wake time, sleep goal, and current sleep debt. If you recently changed your sleep schedule or sleep goal, give it a day to recalibrate from new data.
No. All processing happens on your device. See the Privacy Policy for details.
