Make your course app with BDK

More learners finish, and finishers buy the next course. Your learning platform becomes an iOS and Android app where lesson video plays in the phone's own player, learners record spoken practice, buy course access through store billing and get reminders they said yes to. Your login, your courses and your access rules stay as they are.
