# Mental Abacus Expert vs Abacus Exercise

The clearest difference is ads: Mental Abacus Expert at none against Abacus Exercise's shown. Mental Abacus Expert also leads on monetization model (free vs ad-supported) and iOS requirement (7.0 vs 11.0). Abacus Exercise's advantage is rating (4.5 vs 4.1) and ratings volume (60 vs 7). On price, review sentiment, update cadence and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

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.

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