Loving the app so far!

I honestly think this is such a great app. I’ve always wanted to be quick in arithmetic and one day I saw a video of kids being able to add/subtract large number within seconds and immediately knew that I wanted to learn this method. When I stumbled across this app I thought it was the perfect opportunity and I’m really enjoy it so far. Thank you to the creator of this app!!!!

A GREAT APP!!

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.
