Soroban Drill

The app is well formatted on my screen and I can use it with or without my physical Soroban. Excellent for beginners like myself. 😊

It simply doesn’t work! Just installed it the Soroban didn’t resize nor slide

Perfect presentation in both concept and programming with the user in mind. I have tried many Soroban apps and this is the first one I’ve 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.

I knew little about the Soroban and now I’m able to use it proficiency.

There’s 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.

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.
