Any good android apps for learning German?

I've tried Doulingo and it's too annoying for me (it's repeatetive and offers no customisation at all). I am looking for an app where I can select what to practice (vocabulary, grammar, etc.). If there is no good all in one app, different apps for each task would be fine too.

For vocabulary I've tried voc.lab - It's quite OK (it has flashcards, audio, sentences), but the free version is limited for 150 words only and I would like the auio to be for the whole sentences, not just the word being learned.
