My experience is far better than expected yeah it is quite better, and it is helping me to learn it in a fun way if you are new or beginner then you should definitely try this thanks to the Japanese person who had made the app I absolutely appreciate him or her whoever it is has thought everything that we need to learn about abacus, and it has a proper lesson plan and everything I just appreciate everything in this app for better than I expected, and I don't have any issue currently don't play game

Great for beginners. Excellent introduction chapters. I'm taking Abacus for the very first time in my life and the app lessons are teaching me really well. Keep up the good work. Thanks a lot !!

★★☆☆☆ Akarina · Mar 12, 2026

So I got a right answer, but it was marked wrong (maybe because of a different way on how to count it?)

★★☆☆☆ Jennifer Goudge (Jen) · Mar 3, 2026

Great until lesson 3. Part way through there are required ads (that's fine it's a free app), however, even after letting said ads play, you can't exit the ads to continue the lesson 3 practice. There's an X in the top left corner after the ads, but it does nothing, so you can't access anything beyond two practice sessions into lesson 3.
