Hello! First of all i love this platform, it helped me a lot to make me back to study. Just two suggestions for android. When access to a content unit just to briefly check what it is about and than go out, app marks the content as if I already ready it or done it. So maybe it should be better if it was just marked as read just in the end of a quizz or in the end entire scroll content.
Second, on android it should be more easer if the "Recent lessons" tab would be changed just to a list of "Recent Units". The experience of studying more than 2 different units, becomes a little difficult. Always have to go to settings buttom/View progress report/open browser and check the activity. So if this way could be more short, I guess the app would turn the UX more interesting.
