Good apps, easy to understand. However there is an improvement, when I use Japanese abacus and customise it to 2, during challenge the addition easy, it is still have 6 digits number, where the abacus only have 2 column. Suggest the challenge can adjust according to the customization

The app is extraordinary, super helpful and informative as well. I can use the app to teach my son how to use abacus. Kudos to the devs.
