QR codes have made it easy to share content throughout the smart phone world. With a quick scan you can view websites, text, coupons, and much more. Searching on the Apple App Store, I've found that there are many QR code readers that you get, but the reader by Tap Media is my favorite.
QR Reader (a very unique name right?). Out of all the readers I tested, this one allows the most customization and ease of scanning.
I think anyone looking for a good app to scan QR codes should get this. It is simple, easy and has lots of features.
Download it from the App Store!
