The biggest differentiator is that it doesn't lock you in. With a lot of tracked QR code tools, you end up paying indefinitely just to keep previously printed codes working. With qr-code-maker.app I'm not held hostage by the platform - codes remain usable and I'm not worried about old materials breaking if I change plans or even downgrade to free. The product is also simple to use, fast, and produces QR codes that scan reliably. Review collected by and hosted on G2.com.
Nothing major so far. A few advanced options could be a bit easier to discover like bulk upload, and I'd like more in-app guidance on best practices (print sizing recommendations). But overall it's been smooth and reliable. Review collected by and hosted on G2.com.
