# Personal colorimeter vs QR Code

The clearest difference is ads: Personal colorimeter at none against QR Code's shown. Personal colorimeter also leads on iOS requirement (12.0 vs 17.0). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
