Suggestion: color code the language you're typing in
When you ask us to type in some language:
let's say English-German, you could differentiate them with color, let's say blue-red.
so that when we are asked to type in English the color (red/blue) reminds us in what language to type.
when everything is in black it's hard to notice the little things!
Alternatively, if we're asked for language X and we correctly type in language Y, prompt us to retry instead of docking a heart.
It does this on the desktop version, but I find the iOS app still docks a heart for typing in the wrong language.
We'll be working on making it so that we don't dock a heart when you do that on the iOS app after our next update (which comes out next week & has lots of exciting new stuff).
It's been half a year and it seems to me like the Android app still removes a heart for answering in the wrong language.
