o2o ‑ QR Codes Unlimited

I used this app to create QR codes for several print marketing ads. Very easy to create, analytics are good and seamless with Shopify. Free, which is fantastic. Missing some formatting I like in paid apps (put logo in code, or a frame. around code), but happy to give up for a free app. Love that there are no limits to # of codes, and that I can link to a discount and set landing page
