The formula is on From tryout to habit.
Personal
Read the speaking level check result, do 3–5 minutes of Self practice, and optionally one Live pair practice. Day to day, follow Today's step. Check again in the App after about two weeks.
Child (Family)
A parent tries the product, opens Family, and creates a child account. The child signs in with account and PIN. The parent allocates practice time. A child account cannot sign in on LINE.
Learner (Teaching)
Do the speaking task the teacher assigned. Minutes come from the Teaching pool or from what the teacher allocated. A learner does not usually rewrite the whole plan. See Assign tasks and plans.
