Compared to the ios app, this is terrible. It won't work in landscape mode, messages pop up with no dismiss button so you have to force close the app to get past them, it doesn't seem to be giving me any typing tasks and my 'legendary' lessons are cracked (I thought the whole point of completing legendary level was so that it couldn't crack?). Also doesn't tell me how many points each lesson will be worth. After using the ios app for years, I would rate this unusable.
