Free on the App Store for iPhone and iPad and on Google Play for Android. The online diary and the sleep window calculator also work here in your browser, and there are printables for paper.

What’s inside

Apple Health and Health Connect

Both are off until you turn them on. Then the app can show the sleep your watch or phone recorded in Apple Health or Health Connect next to each night, and save your diary nights there. That estimate never changes your sleep window.

Private by design

No accounts, no ads, and no analytics. What you write stays on your device, or in your own iCloud or Google Drive if you turn on sync. Reminders never show what you wrote. The app’s privacy policy has the details.

Help with the app

Support answers common questions about the app, and the app has its own Help in Settings.
