# Abacus Exercise vs そろばん問題集

The clearest difference is in-app purchases: Abacus Exercise at none against そろばん問題集's 1. Abacus Exercise also leads on ratings volume (62 vs 5) and iOS requirement (11.0 vs 17.0). そろばん問題集's advantage is rating (4.8 vs 4.4). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. そろばん問題集 sells 1 in-app purchase, starting at $1.99 per month. Abacus Exercise asks for nothing beyond the download.

そろばん問題集 holds the better App Store score, 4.8 against 4.4. That said, the two scores are not equally well evidenced: Abacus Exercise has 62 ratings behind it against 5, so its average is the more settled of the two.

Abacus Exercise ships an update every 3 weeks, そろばん問題集 every 6 weeks. Both last shipped on November 3, 2026.
