Great App – Duolingo - Language Lessons Review

I love this app as it turns language learning into a game. However, why the developer chooses to hide how many XP I need for the following level is beyond me. Asking me in German to match “ein” with “a” on level 23 is not helping me. Please give greater practice for higher-level vocabulary. The Japanese course does not adequately mix skills. An entire lesson can be spent on writing. Tedious, as this is not the case in German.
