# Conversion Calculator vs TFPilot

The clearest difference is in-app purchases: TFPilot at none against Conversion Calculator's 1. TFPilot also leads on iOS requirement (14.0 vs 17.0). On price, ads and device support there is nothing between them.

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