Are you worried that your child doesn’t like math, or lacks basic math skills?
Basic calculation skills are the first step to being good at math.

To that end, SMATOOS has created the 'FingerMath ABACUS - addition,subtraction' app, a gorgeous digital learning tool that helps children gain confidence and improve their basic math skills.

Children can learn the principles of arithmetic quickly and easily with FingerMath ABACUS, and build strong foundations for math by using the app to solve math problems of varying levels of difficulty.


✔No complicated instructions. Children learn intuitively and easily.
✔Important concepts are reinforced through a variety of math problems, which can be repeated as many times as necessary.
✔Beautifully designed graphics and sounds were inspired by nature and make this app attractive to children.
✔Virtual awards are given whenever a step has been completed or a concept mastered. Rewarding achievement inspires continued learning and a deeper level of commitment.


✔ Tutorial: The first basic four steps of tutorial will allow children to learn how to use abacus. Through full version, children can learn how an abacus works at their own pace through a nine-step tutorial. The full version is available through In-App Purchase.

✔ Easy, Medium, Hard: At free version, 12 steps of Easy addition problems are provided. The full version has more than 100 addition and subtraction problems of different difficulties (Easy, Normal and Hard) which increase in difficulty as the child’s skills develop.

✔ My Abacus: This is a digital abacus designed to be used like a real abacus. Once children have learned how to use the app, they can play with “My Abacus” and see how their abilities have grown!

✔ Stamps: The app records and retain information about how many hours it’s been in use, the number of steps completed, if any new records have been set, etc. Users can track their own progress as their abilities improve.

Ratings and Reviews



There is a mistake in the first few problems. The abacus does not allow you to move on until you sole a problem correctly. Well, if THIER answer is wrong, what are you supposed to do? just keep guessing. Worthless until you fix this. I would like a refund.

Best Abacus App by far!


Not only will you learn how to properly use a 'real' Soroban abacus, there are also tests so that you (and/or your child) can be sure you've truly mastered what you learned.
Other abac(i?) programs either give just the abacus, with no instructions, or the program is way too 'childish' & cutesy.
The fingerwork, which is essential to do fast calculations with a real abacus, is taught in the tutorial section. This is lacking in the other programs I've used. And the app reacts perfectly to the user's touch. In another program I've tried, the beads lag which makes it difficult to get correct calculations.

What you get:
- An 11-digit Soroban (Simplified Japanese) Abacus
- A Tutorial section
- 3 Sections of mastery problems, from easy to hard.
- and a personal abacus calculator to make your own calculations with.

This is a great app for people who've always wanted to learn how to use a real abacus. It's even easier than having the real thing! This program is especially great if you have had problems with math before. Math geeks will love it as well.
This is an all-ages app from 3 to beyond. I'm in my thirties who loves anything to do with math & my child is three. Both of us find it challenging yet fun.

Hopefully, they will create the multiplication/division part of this program soon...

Good game


Nice graphics and taught me to be quick with the abacus, at least the virtual version.

I must say however that multiplication and division aren't there in this game although the screenshot shows them. Only the addition and subtraction seem to be there. Hopefully the game will be updated with them.

I have used this game for the past month and play with it everyday. I think i have gotten to be good at it. I did read instruction from idirect or some such website i found using google. The tips from there really helped me.

Other games for soroban have crappy graphics. Not only did this one have great graphics, the game itself is cool. There is another game however where you have to write down the answer once you have computed your answer. That may be the proper way, this one isn't bad.

Wish they have multiplication and division, i would really like to learn that on this game.

Good job smatoos.
