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.

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 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.

Exactly what I was looking for! 😊

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