It works like it should and Fast – Quick QR Scan - Barcode Scanner & QR Code Reader Free Review

I've never used a barcode scanner before, and was anxious. This was the easiest app to use I've ever had. It worked perfectly. I used it with iPhone 6 IOS 9.1. I'd like to purchase it and get rid of the very few ads, but don't see a way to do that.
