# CalcFormula vs FormulaPad

The clearest difference is iOS requirement: FormulaPad at 17.0 against CalcFormula's 26.0. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. CalcFormula sells 1 one-off in-app purchase and FormulaPad sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
