# Causality vs QR Code Snap

The clearest difference is in-app purchases: Causality at none against QR Code Snap's 1. Causality also leads on iOS requirement (16.0 vs 26.0). On price, ads and device support there is nothing between them.

Both are free to download. QR Code Snap sells 1 one-off in-app purchase. Causality asks for nothing beyond the download.
