# cFormula vs Calculator

The clearest difference is in-app purchases: Calculator at none against cFormula's 1. Calculator also leads on ads (none vs shown). cFormula's advantage is iOS requirement (13.0 vs 15.0). On price and device support there is nothing between them.

Both are free to download. cFormula sells 1 one-off in-app purchase. Calculator asks for nothing beyond the download.
