Mr Chilli
I love this app, just a beginner but learning fast. Also using the app in conjunction with my own physical abacus. Keep up the good work.
very very good app to practice abacus
i started using this yesterday and ive improved on the abacus more than i have within the week ive been learning. really good app for practicing
No guidance on how to play
It says to pass the grade to answer 10 questions but there is literally no question nor clue of what to answer, just a list of numbers
Needs Bug Repair
I’ve been using this developer’s “Abacus Lesson” which I’m very happy with. So I downloaded this app. Unfortunately, the ones and tens columns are frozen. The other columns seem to work. Once this bug is fixed, I will upgrade the star rating.
Response from developer
Thank you for using "Abacus Lesson" and rating this app! We apologize for any inconvenience. Digits that are not needed for calculation are intentionally prevented from moving. However, there is a possibility of a bug, so we will investigate it. Please wait.
