It worked! Thank you so much.
I've found it here:
Deck Options > Font / Alignment > Font > Text 1 > By Deck > All Decks > $FONT Deck Options > Font / Alignment > Font > Text 2 > By Deck > All Decks > $FONTBTW, isn't it a bit funny to have such a basic thing like a global font setting in
Dock Options, 7 levels deep in menu and only for every side separately? Maybe there could be
Font / Alignment also in
Global Options.

Anyway, your app is really amazing! It has some user interface issues but even though it's certainly the best SRS learning app on the whole iOS platform worth even $29.99+ price.
