# Abacus 2.0 vs Abacus Exercise

The clearest difference is rating: Abacus Exercise at 4.4 against Abacus 2.0's 3.7. Abacus Exercise also leads on in-app purchases (none vs 1) and update cadence (every 3 weeks vs every 16 months). Abacus 2.0's advantage is ads (none vs shown) and iOS requirement (9.0 vs 11.0). On price, review sentiment and device support there is nothing between them.

Both are free to download. Abacus 2.0 sells 1 one-off in-app purchase. Abacus Exercise asks for nothing beyond the download.

Abacus Exercise holds the better App Store score, 4.4 against 3.7. That said, the two scores are not equally well evidenced: Abacus Exercise has 62 ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 50% of Abacus 2.0'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 2.0 ships an update every 16 months, Abacus Exercise every 3 weeks. Both last shipped on October 24, 2026.
