Problems with language in Sheiko App

Hey,

i bought yesterday the app on iOS. The app language is half english and half russian  :o Are there Settings to change the language or is this a bug?

I cant really use the app cause i cant read or speak russian.

Here are some screenshot i made today.

I hope someone can help me.
Many greetings from Germany

Edit: I just downloaded the app on my iPad to see how it works on it. Well, ist works in full english on my iPad but not on my Smartphone.  :-\

Set your language preferences in iOS settings so that English is either your primary or secondary language.
