# CalcSpeed vs Decoy

The clearest difference is in-app purchases: CalcSpeed at none against Decoy's 1. CalcSpeed also leads on device support (3 vs 1) and iOS requirement (15.1 vs 17.0). Decoy's advantage is ads (none vs shown). On price there is nothing between them.

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