I've been curious about this program. So after reading your discussion.I got the app tonight. So far it's great. I've put about twenty something of my snakes on the program. So far It's been pretty easy to use. The saying so easy a cave man can do it is true with this product. It takes a bit of time to enter the information for each reptile. As you can record a lot of details for each snake. As far as the qr code goes it's all in the app. Just touch the camera icon in the app point it at the qr code and it's done. You really don't need a printer. Just email the qr codes to yourself in a PDF. Go to the libary or to a place with Internet access and a printer and print the codes. Like I said I'm new to this app. However I really like it so far. It's better than the index cards I use now. Try it I think you will like it to.
