Ive seen kids do like 10 rows of 2 and 3 digit numbers? just saying. -- SpicySosaa, 2024-03-04 ### ***** "Best App" Could you please add 3 digit multiplication and division? -- Sweet Caroline!, 2020-05-06 ### ***** "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! -- OohOrganic, 2020-04-29 ### ***** "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. -- Just speech, 2019-05-31 ### ****- "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. -- bbshrmn, 2019-03-03 ### ***** "Thank you!" I have been looking for an app to LEARN the abacus/ soroban and THIS is it! -- MaxxHead, 2018-08-13 ### ***** "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. -- SunnyBunny2222, 2018-03-23 ### ***** "Awesome app" This app has made learning math so much fun. I love it!!! -- Kruzer32, 2017-11-23 ### ***** "Great" Simple. Well-executed. Effective. A bargain. -- Limbo74, 2017-02-03 ### ***** "Pretty well done" I have tried a few other abacus apps and I must say this one is the most useful ones. Pretty well done (on the my phone + ipad) and the exercises are very well designed. Thanks for your good work. -- regular_user, 2017-01-06 [View all Know Abacus reviews and detailed analytics on AppTail](https://app.apptail.io/signup?utm_campaign=ai-crawl&utm_content=reviews) ## Know Abacus In-App Purchases | Item | Price | |------|-------| | Remove Ads | $2.99 | ## Know Abacus Discovered Keywords -
