I would like to set up reminders to do my lessons.

1. From the Profile screen, go to Settings.
2. Tap "Notifications".
3. Turn on "Practice reminder" and choose a "Reminder time". Or turn on "Smart scheduling" and we'll pick the best time for you when you forget to practice.

On the same screen you can also choose what else to be notified about, such as your league, Streak Guard, and weekly progress, and whether to receive reminders by push notification or email.
