On price, review sentiment, update cadence and in-app purchases there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Abacus Exercise holds the better App Store score, 4.5 against 4.1. That said, the two scores are not equally well evidenced: Abacus Exercise has 60 ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 50% of Mental Abacus Expert'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.

UpkeepUpdate frequency

Both ship on a similar rhythm, roughly every 3 weeks. The most recent releases landed on June 10, 2026 and September 21, 2026 respectively.
