I'm so close to letting my streak die because of this dude. Fuck him.
My library (and check yours, too!) has free access to Mango Languages, and what I have tried there has been nice. But they don't guilt trip you into doing lessons so you have to keep on top of it yourself.
I ended my streak and uninstalled a while ago. It went downhill when they got rid of the discussion section for the exercises. Add to that stupid sentences I most likely wouldn't say in the real world .
