One of the best educational apps Ive seen

It does all it promises. I have forgotten everything I learned at school but I easily learned again.

It has minimalistic design and very friendly interface, nothing draws attention from the content. It has great customization features - user can set interface due to his preferences to make the process of learning even more comfortable.

I totally recommend this app to anyone who wants to learn division.
