Excellent

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.

Outstanding!

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.

Love it! Best app

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.

Fabulous Abacus

This app makes learning and practicing the Soroban, so easy! I am learning, while teaching my child (age 7). I have no previous experience with the Soroban, but this app makes it so simple. I want to study more each day. Each level advances in a seamless progression. I couldn't be happier with this program.

Better than the other options

This app, as opposed to most others out there, actually teaches you how to use the soroban. Note that the explanations are very -VERY- rudimentary, yet useful. Also the explanations seem to be written by someone with little command of the English language but are decent enough to be understood with some patience. If you know zero soroban, then this app will get you to be able to do some basic math in a matter of minutes.
