Open Settings → Backup, connect your Google account, and create a backup. Confirm the latest backup time before changing phones. On the new phone, connect the same account and restore. The app checks for automatic backup when you open or return to it, or switch away. Changed entries are backed up once 24 hours have passed since the last backup. Use Back up now whenever needed.

Open Settings to choose separate defaults for new timed and all-day schedules on this device. They apply when you create a new schedule. Saved schedules keep their existing reminder settings, and each schedule can be changed separately.
