This app has everything you need to stay sharp on the go. Itโs my favourite Abacus app.
Exactly what I was looking for! ๐
The app is well formatted on my screen and I can use it with or without my physical Soroban. Excellent for beginners like myself. ๐
It doesnโt resize or slide
It simply doesnโt work! Just installed it the Soroban didnโt resize nor slide
Excellent!
Perfect presentation in both concept and programming with the user in mind. I have tried many Soroban apps and this is the first one Iโve really stuck with for practice. I have improved accuracy and speed and always look forward having a few spare minutes throughout the day for fun challenges. Very grateful to the talented person who developed and offered this app.

Very good App
I knew little about the Soroban and now Iโm able to use it proficiency.
Multiplication a rip off!
Brilliant for addition and subtraction. Really good app. However, I paid for multiplication and you canโt do proper multiplication because you only get 4 rods to work on, everything is too close to work on. Complete waste of money. If you could turn the iPhone on its side to get a larger landscape abacus then the multiplication would work. Not impressed

Multiplication costs... but is it worth buying?
Thereโs no description that I found of the multiplication method taught. There is an advanced Soroban method I would prefer, but I'm not going to buy this on the off chance it's the better and (in the west) rarer form.
Good for + and minus, needs landscape mode
Fine for practicing addition & subtraction- if they can add a landscape mode, multiplication & division practice will be feasible and it would be a great app.
