Fluyo released on Android...really disappointed so far

I've played it a bit and it seems super buggy, it gets stuck a lot. Lags. I'm encountering errors where if it asks to translate a verb into English and I say "to bite" it only wants "bite" and considers me wrong. Tried a language I'm a2 at and the words it started throwing at me were weirdly advanced, even though the description of the level said "I can introduce myself and say a few basic sentences" The mandarin flashcards built in don't show pinying, which is a major bummer. Really not impressed so far.
