# iCalc Math vs 试题库

The clearest difference is in-app purchases: 试题库 at none against iCalc Math's 1. 试题库 also leads on update cadence (every 3 months vs every 12 months). iCalc Math's advantage is iOS requirement (7.0 vs 17). On price, ads and device support there is nothing between them.

Both are free to download. iCalc Math sells 1 one-off in-app purchase. 试题库 asks for nothing beyond the download.

iCalc Math ships an update every 12 months, 试题库 every 3 months. The most recent releases landed on June 25, 2026 and October 1, 2026 respectively.
