It could have a standard report after each lesson with the words, grammar and other rules learned and also mistakes to avoid. I need to download another app to fill these lacks. Also could have an iPad version and horizontal orientation as well. What it needs in a nutshell: reports after each lesson, written lessons and writing practice (like Duolingo, Babbel, etc) and an iPad version. It's a wonderful platform to study conversation, but not for reading and writing.
