Sundial support

Email support@sundialhabits.com for help with your account, sync, or anything in the app. Please include your iPhone model, iOS version, and what happened. Never send your sign-in code or password.

Getting started

Enter your email address and use the six-digit code we send you. Add a daily habit with the + button. Tap a habit to mark it complete, or tap again to undo.

Offline and syncing

After signing in, your habits are saved on your iPhone. Check-ins and new habits work offline and sync when you reconnect with the app open. Use You → Sync now to retry. Sign in with the same email on another iPhone to see your synced habits.

History and archived habits

History shows your last 14 days of completed habits. Touch and hold a habit to archive it. Restore archived habits from You.

Delete your account

Open You → Delete account and confirm. This permanently deletes your live account, synced habits and history, and the local data on that iPhone, including unsynced changes. An internet connection is required. If asked, sign in again and retry deletion.

Other offline devices can retain downloaded copies. Remove Sundial from those devices to remove those copies. Deleted account sessions cannot sync or restore data to the server. You can contact support if you cannot access your account.

Privacy
