# Calculus Formulas vs SimpleTools

The clearest difference is iOS requirement: Calculus Formulas at 15.1 against SimpleTools's 17. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Calculus Formulas sells 3 in-app purchases, starting at $2.99 per 7 days and SimpleTools sells 2 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.
