How kids should be taught Used this to help my 7 year old son. He's now best at maths in his year (3) and year above (4) uk. Need division tutorials. Thank you


Best soroban app Good UI. I wouldn't mind a more in depth tutorial, but that's nitpicking.

Akshay Chourdia

THIS IS Soo GOOD FOR LEARNING ABACUS I suggest you that u can Also add tutorial of division

Omar Miah

Great learning tool Love using this app. It's teaching me how to do fast maths. I found getting my head round using a soroban abacus really hard. This app has really helped. Now I can teach the kids!

Ibis Prevedello

You should consider making it into a game, it is very challenging.

Peter Allen

Fantastic app Nice, simple design with easy to understand tutorials. Wish we were taught this way in the West!

Timothy Ahn

Almost perfect! It would be nice if we can move the heave and earth beads at the same time. Kind of a hassle to move them separately. Other than that, Great app for practice at everywhere. I practice using this in school and yeah

William Babcock

Amazing The practice modes are great. I enjoy that I am trying to constantly beat my best time. It would be nice to have the ability to challenge friends for the best time, though it is in no way a deal breaker. This is an amazing app.

Chris Musser

Great for reluctant abacus learner My son has resisted learning to use the soroban, but when he saw me playing Simple Soroban, he suddenly got interested!


Great app! I love soroban and this app makes it easy to learn and carry a virtual soroban always with me!

Graham Davies

Fantastic soroban app This is the app to download if you are looking to lean and master the soroban Japanese abacus. Tutorials are clear. Game / practice challenges are great. Keep up the good work! If you are looking for features - adding the soroban exam style of practice would be good. ie lots of add/subtract in a row to get to the right answer. Multi touch would also be good the practise correct finger method.

Morgen Peschke

Best soroban abacus in the Play store This is the best soroban I've used. There's one other that's great for getting started, but having completed the exercises there I've found myself using this exclusively.

Roberto Murakami

Soroban Made Easy Great tutorial, very didactic on how to use the Soroban. This is one tool that you must learn the theory and practice to truly understand. This app does just that.

Alan W

Best Soroban Training This can take you from the basics to fairly advanced. Great app.

Alison Melrose

I love this app. It's my favourite at the moment, suits my nerdy nature! Multiplication is a doddle, but subtraction has me stumped :-( Off to find a quick tutorial..............

Antonio Nodarse

Excellent & Elegant I just recently began learning the Soroban so I may teach my 5yo. This app is great once you understand the basic operations of a Sorban. Well done, Bruno! (would love to see a division module in future updates) :-))

Michael Tward

Beautiful, good practice, active developer! I love how the beads change colour when counted, and how the totals show up below each rod (would be nice to toggle this feature on or off). Please add a manual reset button and also include division!

Mr. Ian Fisher

Beautifully designed lacking a reset button but other than that I think it's the best looking soroban app and has a very smooth bead action compared to some of the other soroban apps

Francisco Corrales Morales

Good. Need to: 1. Feature request: Enter a number manually. 2. Bug: The display when you answer correctly a question is too fast, I can't see anything.

Mukund Bhalerao

Loved it!!! Its amazing both on free mode and exercises ....

Handan Altintas Pusatcioglu

Great app to learn soroban Thank you for the app. Could you include a version for older android versions?

Sadman Zahid Khan

Great app. Its a very good app. But I just don't know how to divide. It'll be great if you add a tutorial soon.

Andrea Cornaglia

great design and easy to use!

Armin Bundavica

Really nice app but.. Great job with the app.. I've progressed enough to the point I can do the easy addition through mental image of the soroban. But one thing that bugs me a bit is that you can't flip the app the other side around, it may sound weird but when I'm charging my phone it gets a bit uncomfortable for my right hand so if there was a possibility of flipping the app that would be wonderful. Thank you!

Russ Jorgensen

Great app. Wish I could disable the vibrator in challenge mode to save battery.

Lynn Hall

Simple Soroban A very good app for practice

Urfin Roger

Great app, much better than many nonfree apps

Jesus Smith

Very Good Excellent app. Needs the ability to repeat problems and the ability to create your own. The ability to remember a list of challenges would also be welcome. Would pay for a version with these simple additions.


Simply Great Tutorials are quite helpful for the beginner. Needs a tutorial for division calculations, otherwise it's incomplete. Is it kept for paid version? Also, need to have a "Redo" button with slow activity re-done. Results shouldn't cover up the beads.

tetsuko uehira

This has tutorial. People who knows or has good amount of training of addition, you can get good practice of addition and subtraction, and learn multiplication and division by this tutorial. I love this app. Only thing this app. is missing is step by step tutorial of addition. I learned it by doing over 100 problems to come to second nature. Please add more detailed addition and subtraction tutorial. I would pay for that upgrade for my kids.

Lyman Johnson

Robust, simple, effective! However, I'd like an option to turn off the underline that appears to tell you that you've made it correctly through half the problem. I'd prefer to have no hints along the way.


Good app Good app. Everything is fine only need to add button to restart new challenge instead of keep back to menu option every 5 time exercise. And could be better if the result not pops up and cover the screen, so user can also exercise to guest the answer by seeing the result of the grain.

David Hartman

Needs Division Tutorial I love this app. I've worked all the way to division and had to stop because of the lack of a tutorial

Fabian Mendez

The best by far.. Awesome app, it's been ages trying to find the time to learn soroban reading books and practicing. With this app just took me a few hours to feel confident with the basic calculations, thank you!

Gary Bennett

Wonderful Looking for an App to learn abacus to help my son with his maths, now addicted myself. A really well designed app.

Dejan Markovic

Exelent. Tutorials are great. Needs division tutorial.Is there tutorial for mental abacus?

Andy Grey

Fantastic Exactly what I was looking for to help learn the soroban!

DJ Machani

Best Abacus! I use it as stress buster

Sriram Malladi

The best in the Play store With the addition of themes it is now the best of Soroban on the play store. Kudos to the developer for keeping it simple especially since the kids will benefit the most.

Jonathon Brace

Excellent app Really easy to use. It's helping my maths skills a lot.

Ken DeJesus

Simple Soroban Excellent in so many levels!!!

Steve Gibson

Simple soroban is by far the best soroban app that ive been able to find. I use it ALL the time. Best app on my phone! Thank you.

mu chad

Cool and useful

Zach owen

Just wonderful It's good to see an app that is functional, helpful, and not teaming with ad's. It has tutorials all the way from 2 digit addition to 3 digit multiplication. This app is so great it even has a free play. Check out out!

hemang doshi

Tutorials Please please and please give tutorials of division also.

Ric Moore

Great with one nit Needs instruction for division, but otherwise excellent!

Sharen Myers

Lovè it, awesome art Most awesome game. Keeps your mind thinking and I really thank you

joy bagchi

colin baguley

Shikamaru Nara

Nguyen Phuoc Thuc Phan

Great abacus app Very efficient app to learn to use the abacus. Looking forward to a tutorial for division.

James Millard

JM Roberto

Mokkilpala Sajitha

Good. Wish the tutorial was comprehensive

Alireza Davami

The best abacus Install and have fun

Syed Muhammad Noor-ul-Hassan

No. 1 Soroban app on Google play store This app teaches the Soroban step by step and consists of many tutorials. Actually I came to know the Abacus on 18 September 2015 and on the very next day i.e. 19 September 2015 I was near to an expert just by using this app. Awesome awesome awesome app. It is not so simple to program an app on Android. But this app makes one to understand the Soroban Abacus very very very very very very very very very very easy. And the 2nd best app is "know abacus ", you can keep both. Enjoy

Milgre Asis

Thumbs up for this app! I really love the app. It's cool and I'm really looking forward for the tutorial in division. I use this app when I'm bored and it helps me practice my accuracy and speed in answering simple arithmetics. Well, I can only suggest that the given problems should be more than 5. There should be an option if you want to answer more than 5 problems, like 10, 15, or even 20. :)

Sarinah Tambu

Excellent app!!!!!!! THIS IS AN AWESOME APP, thank you for the opportunity to use it. I use this for daily practice. The fact that it verifies your answers after each step is great. The interface is clean, simple, and reliable. I have not detected any flaws. I am using this after learning the basics of the Soroban on YouTube videos. The only wish I have is that you can re-do a problem when you get it right so that you can re-work it again as sometimes I get it right by fluke.

Kate Leonardo

Lots of fun. Easy to use. Thanks dev! Using this to learn how to use soraban. Would be nice for information on bead manipulation, mainly one handed (aka japanese as apposed to indian two handed) since this is titled simple soraban. Only real gripe is that it automatically says answer is correct before I have not technically completed the problem. Maybe implement check answer button? Enjoying this app. Thanks!

Blits Craig

Amazing I did a presentation over the abacus in my public speaking class and I would have done terribly if I didn't learn how to use it through this application. Thank you!

First Name Last Name

1. Please add the ability to manually increase rows and move decimal place. 2. Please give the Option for the Chinese style abacus for hexadecimal calculations. 3. Please save our calculations in case the app closes or is interrupted. Other than that, it functions well.

Matt Stoodley

Great Loved learning on this

Misael Gómez Soria

Great soroban Is a very good app fot learn math :)

Koby Goldberg

Love it! Best way to learn the soroban! I love it the way it is, with all its features and options! I've ended all stages and got stuck at the division part because there is no tutorial. When do you expect to have that tutorial added? I also heard it is possible to calculate roots using the soroban, and would love to have it added to this app as well. Thanks!

Kamirin Akhu Ra

Divided tutorial There is not tutorial fo divided section.

Brian H.

Excellent. Great for practicing. With division tutorial, would be near perfect. I'd like the option of hiding the digits at the bottom, and the underlining "hints"(it's easy to get in the habit of relying on them).

Benny Ben

Very interesting app; I enjoy learning how to use it. Please add the Tutorial for the Division operation!

Karl Montague

Addictive and fun This is a great introduction to the soroban abacus. Some of the tutorials could be expanded, but quite simple to understand.

Lyman Johnson

My girlfriend keeps stealing my phone! Please make an iPhone version for her :)

Manuel Soto

Excellent Easy to use, good tutorial and excellent test to improve the performance.

Ricky Tan

Needs division tutorial. I will rate it 5 stars if you will add tutorial for division.

prem kumar

Good App Will make you expert from the beginner level

Justin Reese

Excellent! Clean well organized great game! Thanks for creating and sharing.

Sandy Coupe

Simple Soroban Taught mastery of adding on the "abacus". Has further skills if you pursue them: subtract, multiply, & divide!

Olesinski Oleg

Cool Adorable application, thx a lot

gogula srinivas

Well done. But where is tutorial for division.

Liam Kane

Simple and clean Very smooth running app, barely noticeable adds, and a solid if simple tutorial on how to use it.

Robin Wood

Really good, works well

Des Mann

Abacus Very good as an adding aid, no wonder Japanese children are good at maths.

Seth Riedel

Move the equations to the left side! Overall, I like the app. I wish that when you are doing the math quizzes, the equation was on the top left side rather than the top right. I find that my right hand is in the way of viewing the numbers and as a result, I often mix the numbers around in my head and perform the wrong equation. Other than that, it serves its purpose and I enjoy the app. If the aforementioned issue is addressed, it would be a 5 star app in my opinion.

aion shiro

Simple and smart Its a great app to start learning abacus. The only thing needed so the pop will be a reference is tutorials for the remaining ones

Eric Del Rio

Perfect abacus This abacus is perfect for my 7 inch tablet. It also has a tutorial on how to use it, and i learned fast. Now i'm doing arithmetic on it and im very happy. You can't go wrong with this abacus app!

Larry Jensen

The Best! A stable app that works great. I would love to see it keep track of average times along with the top score it already records. It also needs better tutorials.

Kamireru Boroboro

Beauty in simplicity I have not read builtin tutorials, so I cannot comment on them. The rest of application does exactly what it promises without distracting user with unnecessary bells and whistles. I do miss ability to use 9 digit soroban for multiplication and division though.

Derek Wong

Perfect Soroban app This one let's you pinch, which is an essential move.

Nicole Fontenot

Very nice Un-intrusive permissions. Tutorials for basic mathematics algorithms on the soroban. Keeps track of how efficient your calculations are.

Pearl Asteria

Yay Its nicely made.. need a tutorial for division too

Morisse Makki

I liked it because it teaches the kids how to (Add,Subtract,Multiply,Divide)

Robert Deland

Takes me back to my youth As a young man I had (still have) a soroban. I practiced with it, becoming very good. That was more than 40 years ago. Your app is perfect. No adverts, and very nice test problems. I have proved that I am out of practice, but I am having fun.

Gary Jamieson

Great for beginners! I knew nothing about operating with an abacus before using this app. A couple of days with this and I'm getting really fast. My daughter is using it now too!

Scout A. Loud

Cannot add my own equations, it will only let me enter numbers but no function...

robin strickler

And I don't even like math! It's addictive and engaging. I'll be delighted when the division tutorial is out. You've done a great job!

Srikanth Chevvakula

It's good I wish that, while attempting answers, the value indicated by abacus should not be displayed.

Ramon Castro

I love this app Cannot think of anything it's missing.I can spend hours on it. Great job.

Badumka Duke

Great for training Would be good to enter result after solving. Perhaps as a setting. Now it doesn't challenge you to read what you just wrote.

Aric D

Excellent! Exactly what I was looking for. Simple effective design, and fun to use. This is great for beginners looking to learn the fundamentals of the abacus.

Jim Dowdell

Great! Tried many of them, this is the first one that actually works! Excellent tutorials. Well done

Dániel Vásárhelyi

simply perfect it comes with tutorials, simple but powerful interface, and limited permission need!
