# NS3 vs QR Code Expert

The clearest difference is device support: NS3 at 3 against QR Code Expert's 1. NS3 also leads on iOS requirement (12.0 vs 26.0). On price, ads and in-app purchases there is nothing between them.

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