Edit: I thought the first lessons were really good, but the explanations started getting more and more confusing, now I'm at Level 7 and read the lesson many times but still don't understand it. That's why I removed two stars, I feel that it wasn't worth what I paid for... Great app! I'm really learning to use the abacus with it. My only complaint is that it's hard to manipulate the beads correctly sometimes, and it would be great if there were lessons with more advanced operations.

Exactly what you need to learn how to use a 4+1 abacus. It teaches this new skill in an enjoyable way and I can see myself improve and get faster every day. The small cost is justified and worth paying to pursue progress. I really appreciate this app was created.

This app is awesome! Thank you so much for making it- in one day I learned how to read the abacus, add and subtract with double digits. I ordered an abacus and this is exactly what I was looking for to get me ready for it. I gladly paid for this app :)
