The best app to learn soroban abacus. It's easier if you have basic knowledge first
★★★★★Bill Piazzetta· Jan 11, 2023
Edit: I thought the first lessons were really good, but the explanations started getting more and more confusing, now I'm at Level 7 and read the lesson many times but still don't understand it. That's why I removed two stars, I feel that it wasn't worth what I paid for... Great app! I'm really learning to use the abacus with it. My only complaint is that it's hard to manipulate the beads correctly sometimes, and it would be great if there were lessons with more advanced operations.
