The app is nice but has so many bugs (i develop apps as well) the check box disappears. The conversation thing is a waste of time, would be good to be able to bypass it. I was hoping for more from this app l, but it seems to be a cross between rosetta and duolingo. So easy to guess answers rather than learn. Similar to duolingo where you can practically go through app by guessing and only learn 10%.Was really hoping this would be better. You need to short out your bugs mate.And the app is jerky
