I’ve always wanted to learn Abacus, but I can’t never understand it even if I watched a lot of videos. I also don’t have time to watch long videos, this app gives you simple explanations, but is easy to understand!! I would suggest everyone who’s having a hard time learning Abacus to try this app!! This app is really helpful! Thank you so much for the creator of this app! 💗💗

It works well. I like it

I had an itch to practice abacus after watching some Asian dramas. I remember learning it in elementary school but I completely forgot how to do it. This is the Japanese Abacus with 1 bead on top and I think I originally learned the Chinese Abacus with two beads in top. Despite a few misspelled words in the instructions, I think the instructions are easy to follow and the practice exercises are straightforward forward. I am not a math person, but there is something kind of soothing about calculating with an abacus. I like the sound too. I recommend.

Very good practice

I’m an adult trying to teach my kids how to use an abacus, even though I never learned. This app is great practice. The explanations are better than YouTube.

Great learning tool
