# PilotCalc vs ZipMaster

The clearest difference is device support: PilotCalc at 3 against ZipMaster's 1. PilotCalc also leads on iOS requirement (13.0 vs 17.6). On price, ads and in-app purchases there is nothing between them.

Both are free to download. PilotCalc sells 5 one-off in-app purchases and ZipMaster sells 3 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.
