Know Abacus

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.

This is a great App! My only suggestion is to allow the function to turn on and off the number indicator. By not seeing the number will challenge the user to be confident in his or her answer. The user would not be able to advance to the next question unless they get it right. If the user struggles then they should be able to turn on the function to see the number indicator to help them find their mistake. Make sense?

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.

Please please add more content 3,4,5 digits! I would live to have an update, even if I have to pay for it! Highly recommend this app.

I have been looking for an app to LEARN the abacus/ soroban and THIS is it!
