Simple Soroban is my favorite abacus app. The only times I have had any problems with it have been the fault of a dirty screen -- easily fixed. The swipe to reset feature is a nice addition. The only thing I might wish for would be a few more columns. Nine works for me most of the time, though.
I was first captivated by the abacus as a child & still have two soroban which I believe are a great mental exercise & stress-reliever. This app is the best of several I have tried. The tutorials are clearly written & in my opinion perfect for an absolute beginner, while the challenges are ideal for marking one's progress over time. This app is a fun way to pass time while waiting for appointments, etc., & a perfect introduction to an ingenious device that I feel is still a great learning tool in this age of technology.
I have had this application for a while and I still absolutely love it! I am glad it is still being updated/ added to. . . I thought this app was perfect already, but the new update adding the swipe to reset thing made it better! I still use this app and appreciate the update!!!
Simple and easy to use. Would be great to have even more challenging problems in hard mode with a slightly larger abacus greater than 9 columns.
Simple and easy to use. got this app for my kiddo and now i am getting addicted to it. i like the challenge mode and it really tests you. Better to use this app than playing games.
It is a phenomenal soroban learning app. First for a beginner, it has a basic tutorial so that one can start to learn without an external learning source. Second, as the app throws multiple calculations, it has intermediate indicator that shows correctness, that is, for example, 22+60-5, if the intermediate calculation, 22+60 is correctly answered as 82, it will be underscored. Though this seems rather inconsequential, it shows that the author of the app put a lot of thought making the process of learning the soroban as painless as possible, by taking advantage of the modern electronic environment. That is, if you get the intermediate calculation wrong all subsequent calculations will only yield the wrong answer adding to the frustration of the learning process by needing to go back to the beginning and starting all over again. Here, there is a way to check to make sure you are on the right track, by giving you feedback and giving you a chance to correct your mistake before moving on. One more feature that might be helpful to a beginner might be a single click button that goes back one step in calculation, just in case you forget the intermediate answer. As for keeping you challenged and interested, the series of calculations is timed and shows how you rank against the average. It's a good way to keep tabs on your progress. Afterall, you want to get faster and faster eventually being able to do this mentally. Well, at least that is my goal. Thanks for a great app to make the process enjoyable and pain free as possible.
* Moved "correct answer" box to bottom of screen so it doesn't interfere with the content.
* Added a "swipe to reset" gesture (enabled via settings). User can now swipe from left to right to clear the Soroban.
