The approach to learning and the abacus itself and method are great. The English could be clearer on instructions though and there were some spelling errors.

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.

I've tried a few other abacus apps and feel this one allows breaks concepts down into smaller components which allows you to master each step before adding more. It's also easy to revisit a certain aspect of skill that needs brushing up. This is my favorite app so far.

The graphics, transitions and animations of the app can be developed further... In addition to that, it would be great if there was also an option to change the theme of the app and the users to have a choice among the defferent designs of themes the app could accommodate.
