# PlanPro vs Key Calculator

The clearest difference is in-app purchases: Key Calculator at none against PlanPro's 1. Key Calculator also leads on iOS requirement (12.0 vs 15.0). On price, ads and device support there is nothing between them.

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