Not begginer friendly at all, when you go to the practice on lesson 7, there are just a lot pf problems and it would be good to know if you answered wrong right after you submit your answer. It just sucks and a beginner can't really learn that way. We should know where we commited a mistake before giving us another problem. Ick.

A well thought-out and useful app. Great for learning or relearning basic maths Suggestions are to have the option of turning the sound off as it can disturb others when I use it on the train. Also needs a part of the app that is a pure abicus when the user comes to the end of the lessons. Last part is the adds. I would have preferred to spend a few dollars on this app and own my copy outright than experience the advertising.
