★★★★★ Govind Anilkumar · Mar 23, 2026

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 !!

★★★★★ Kehsiav Oaaa · Mar 24, 2026

It's actually a really good app for learning about how the abacus works. I've been using this app for 30 minutes, and I feel like I've learned a lot already 😅

★★★★★ Dnice · Jul 5, 2026

Why I love the app is because when I had to go for a quick math competition I didn't know it well unt I'll l I searched online for an app that teaches people quick math, and I found the app, and it really helped, and I got 1st position and that's why I love this app

★★★★★ Suma Kn · May 7, 2026

Best aap to learn abacus both for children and adults and all those who r interested in abacus

★★☆☆☆ 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.
