This app does a great job teaching the abacus skills sequentially and slowly and then incorporating older skills with new skills into random practice. It teaches multiplication and division as well as addition and subtraction. Suggestions for improvement would be to add practice for larger numbers and teach multiplication with two and three digit numbers. Also, it would be nice if you could turn off the number indicator to give learners more practice reading the numbers. This app is so good, I would pay money for an upgrade. It is the best app for learning the basic concepts of the abacus that I have found.

Wow, again! You read my past review and made some improvements. Thank you!

Currently, the settings allow single digits and double digits. It would be great to have the option to increase the digits to 3,4,5, and so on.

I can’t say enough about how this app has helped me increase my addition and subtraction skills.

I really enjoy the mental feature a lot!

One of the better training apps

Little clunky but works well and is a good app for learning the abacus. Lots of settings. Goes a bit harder with a setting but wish it had an advanced mode and even get into decimals etc. I also can’t figure out how to get rid of ads.
