Valued team, Developers, user,
my person used to android, was challenged to change setting (espacially language) on an iphone but unable “blind”? to find similar settings, menus on iphone. Maybe somebody feels inspired not to only help out iphone user in regard of language settings but to work out something like in the sample Comprehensive manual for Sārahārī-Saṅghaṁ (Delta Chat) 
Originally thought interface would have similar structure.
