# Calculation vs Formula

The clearest difference is ads: Formula at none against Calculation's shown. Formula also leads on update cadence (fortnightly vs every 2 months) and device support (3 vs 1). On price, in-app purchases and iOS requirement there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Calculation ships an update every 2 months, Formula fortnightly. The most recent releases landed on October 28, 2026 and October 24, 2026 respectively.
