The GoTandem app is available in the languages below.
If the languages above are not mentioned on the GoTandem website or on the description of the GoTandem app, they are still available. I have wrote the Back to the Bible ministry, and the person who works there wrote me and told me the different language versions are available on the app.

If you have any questions or need help finding a particular video, tract, book or any other Christian resource in any language of the world, please contact
