# iformula vs MathEquation

The clearest difference is in-app purchases: iformula at none against MathEquation's 1. iformula also leads on update cadence (every 2 months vs every 6 months). MathEquation's advantage is iOS requirement (14.0 vs 17.6). On price, ads and device support there is nothing between them.

iformula ships an update every 2 months, MathEquation every 6 months. The most recent releases landed on June 10, 2026 and September 23, 2026 respectively.
