# Calculator vs PrefixCalc

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

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