# M² Smart vs QR Code

The clearest difference is ads: M² Smart at none against QR Code's shown. M² Smart also leads on iOS requirement (14.0 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.
