I started working on it almost 4 years ago after moving to Berlin, and discovering how crazy-hard learning a language was, and how ill-suited apps were for getting students to any kind of conversational fluency. So I spent about 2 and a half years going through multiple iterations of the app while incorporating elements of different language learning techniques including audio-book courses, Youtube channels, Assimil books, shadowing, tutoring, and of course other apps.
About a year ago I started working on it full time, and started collaborating with a Youtube teacher to produce content. We ended up really stressing humor and fun as a guiding principle of content creation, and think in the end we've made a pretty unique app because of it.
Anyway, I'd love to get your guy's feedback on it! There is an walkthrough video on the home page if you aren't learning German and don't want to register.
