Built for how the world actually studies

Most people who use this curriculum are not on fast, unlimited connections. The app is designed around that, not in spite of it.

  • Watch every lesson The full seminary curriculum — video, audio, manuscripts and study guides — on the device already in your pocket.
  • Works offline Download a lesson while you have a connection and study it where you do not. Built for places where bandwidth is the constraint.
  • In many languages The same curriculum, translated and reviewed by partners around the world.
  • Picks up where you left off Start a lesson on your phone and the app remembers the spot — no account required to begin.

Help us test it

The app is in closed testing on iOS and Android. Testers get it early and tell us what to fix before it reaches the stores.

Testing is invitation-only for now. Want in? Get in touch and we will add you.

In the meantime, everything is already here in your browser — browse the free courses .
