Verdict

The call

The clearest difference is in-app purchases: Z Amp at none against QR Code Generator's 10. Z Amp also leads on ads (none vs shown) and iOS requirement (15.0 vs 17.0). QR Code Generator's advantage is update cadence (weekly vs fortnightly). On price and device support there is nothing between them.
