Ad close button not working
I really like the app, but the ad close button is not working. I cannot dismiss ads on both iPhone and iPad, and it forces me to restart the app. とても良いアプリだと思っていますが、広告の閉じるボタンが機能しません。 iPhoneとiPadの両方で発生しており、広告を閉じることができずアプリを再起動する必要があります。

Excellent Language App
I have many language apps. They all seem to do word to word translations. This is the only app I found with tips so your phraseologysound authentic. It is the app I have been looking for.

Add CEFR to more than English learners!
App is mainly only geared towards English learners. Most of the good features that would draw interest aren’t available for any other languages. The CEFR tracking is a powerful feature that drew me to this app; mainly because I want Spanish and French CEFR certifications in the future. This would have helped tremendously towards my goals. This feature should at least be available for Spanish learners being that Spanish is in the top 3 most learned languages in the world.
