How do I set up 2Do on a new iPhone, iPad, Mac, or Android device?

If you already use 2Do on at least one other device with sync enabled:

1. Install 2Do on the new device and open it.

2. Open Settings > Sync and pick the same sync method you've been using on your other devices.

3. Sign in with the same account.

4. On first sync, choose Replace local data — this pulls everything from the cloud down to the new device, leaving the cloud copy untouched. If instead you've just restored from a backup and your device now has the freshest data:

5. Set up sync the same way.

6. On first sync, choose Replace server data — this pushes your restored data up, replacing whatever's currently in the cloud. If you're unsure which side has the freshest data, create a backup first so you have a recovery point either way. On Mac, use 2Do > Settings > Backups > Manage Backups > Save as.... On iPhone, iPad, or Android, use the backup option in 2Do's settings. See: Sync overview (iOS), Sync overview (Mac), Sync overview (Android).
