# iCrosss vs Mathematical Playground

The clearest difference is review sentiment: iCrosss at 92% against Mathematical Playground's 22%. iCrosss also leads on price ($0.99 vs $1.99) and iOS requirement (5.1.1 vs 17.6). Mathematical Playground's advantage is update cadence (every 2 months vs every 11 months). On ads, in-app purchases and device support there is nothing between them.

iCrosss costs $0.99 and Mathematical Playground $1.99 up front. Neither carries in-app purchases, so what you see is what you pay.

iCrosss ships an update every 11 months, Mathematical Playground every 2 months. The most recent releases landed on October 19, 2026 and October 11, 2026 respectively.
