I wasn’t able to check out your app, but it sounds like you aren’t a speaker of Arabic. If that’s the case, you should be careful about how and what you translate and more importantly if you should translate at all. Like with any decent translation work, google translate isn’t the way to go, don’t listen to anyone who says that! You should not only have someone fluent in both languages, but someone who understands the context of the material itself. On top of that I would suggest running it by another person to look over to come to a final copy. Again, with what you shouldn’t translate isn’t always obvious and sometimes changes depending on the language. If enough people use a common term, then you should too.
