# Calculation vs PrefixCalc

The clearest difference is ads: PrefixCalc at none against Calculation's shown. PrefixCalc also leads on device support (3 vs 1) and iOS requirement (12.0 vs 16.0). On price and in-app purchases there is nothing between them.

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