A simple soroban abacus that also shows the number representing the value of each column. An abacus is a tool that has been used since ancient times to calculate. Calculations with numbers in the millions have been performed using the abacus, showing that it is a powerful tool. Mental math can be performed incredibly accurately by those who have mastered the abacus. And after witnessing some incredible mental math skills by a person who has used an abacus during his early years as a salesman, I decided to create a "beginner's abacus" based on the soroban abacus, which is a Japanese variant of the abacus. I hope this app will be of use to many people who are starting some interest in the abacus. [ Usage ] : = swipe up/down on the beads to make them move. = Shake the device to reset the beads. = Numbers on the top show the "actual" numbers of each column

Abacus Exercise holds the better App Store score, 4.5 against 2.6. That said, the two scores are not equally well evidenced: Abacus Exercise has 60 ratings behind it against 10, so its average is the more settled of the two. Written reviews complicate that: 67% of Abacus's written reviews are positive against 46% of Abacus Exercise's, so the app with the better star average is not the one people write more warmly about.
Abacus ships an update every 44 months, Abacus Exercise every 3 weeks. The most recent releases landed on October 6, 2026 and October 8, 2026 respectively.
