thank you for your answer.
so it is "just" a matter of somebody writing down the words in the app since the translation of course has been done as we do have german hymnbooks?

i am guessing with the bible it there might be a problem with copyright or something aswell - i am not sure of the exact reason but it might be the same reason why we cannot have a quad combination in germany. is that possible?
is there a way to volunteer for those tasks? i am not a programmer but i think if somebody would show and explain to me how and where i would have to write the hymnbook i would certainly do that.
