For all you selfish “make this English” people

If you’re unhappy with the fact this app—that specifically targets a JAPANESE audience, is not in English, then uninstall it or learn the language. Why download an app you can’t even understand and demand they translate it into English for you for when YOU should be the ones to learn to R E A D Japanese instead. I think that’s more fair than expecting everything to be English for you like it’s on some silver platter just because this app is accessible to the western region. This app can stay in Japanese, and I won’t have a problem with it. Why? Because I took the chance to LEARN the language. I can READ Japanese. I can even SPEAK Japanese. So that if I ever want to use something that’s in Japanese, or speak to someone in Japanese, I’ll be EDUCATED with the language. Not be some self-entitled person demanding and expecting everything to be in English to things and/or places that are foreign to me. Anyways, to the App developers: LOVE THE APP. it’s so cute!

I think you should put this all in English. EVERYTHING. If you can read THIS then you can most certainly write it! I'm sick of such great programs created and they won't think of other countries who might like to try it. I can't even read the darn thing and it just blows my mind that in this universal world you'd at least take into consideration BEFORE releasing this product that other languages are to be available.

Very cute app! My only reason for giving it a four star is because it is only in Nihongo (Japanese). Does not bother me because I love Nihongo, but I'm not very fluent in it so I am unsure what it all says. Please do an English translation and I will rate go (5) stars! :) Arigatou gozaimasu!!!!!
