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 password or password-reset link.

Getting started

Choose Sign in with Apple or sign in with your email and password. New email accounts receive a verification link. Tap + on Today to add a task or habit. Tap the checkbox to finish it, or tap its title to edit.

Plan your day

Capture an idea in Lists → Inbox or add it to a personal list. Planned For chooses a work day. Deadline records the date by which you need to finish. Choose Tasks brings open tasks into Today. Earlier lets you revisit unfinished plans. Set Remind Me when you want a notification at a specific time.

Offline and syncing

After the first sync, tasks, lists and habit check-ins save on your device. Offline edits sync when you reconnect with the app open. Use You → Settings → Sync Now to retry. Sign in the same way on another iPhone to see your synced habits. Apple's Hide My Email may create a separate account from one using your personal email address.

History and archived habits

You shows your habit calendar and streaks. Tap a calendar day to change its check-ins. Open a habit to archive it. Restore archived habits from You → Settings. Finished tasks appear in Lists → Completed.

Friends and sharing

Open Friends to share a seven-day invite code or enter a friend's code. New habits default to Friends. Choose Private in the habit editor to keep a routine to yourself. Eligible shared check-ins appear in Friends, where people can Cheer. Stopping sharing withdraws the cards when friends next sync. Tasks and lists are private.

Use a check-in's menu to report content or block a person. Blocking removes the friendship and prevents reconnecting through a code. You can unblock people in Settings; doing so does not automatically add them again. Contact support about urgent or unresolved reports.

Delete your account

Open You → Settings, tap your account email, and choose Delete Account. This permanently deletes your live account, synced tasks, lists, 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.
