The Android-only app from Simple Design is one of the most popular QR code scanner apps. It’s free to use and lets you save QR codes to your phone or easily share them with friends.

Your iPhone’s built-in Camera app can scan QR codes, and it’s as easy as taking a photo. Here’s how: Open the Camera app and hold your iPhone, so the QR code appears in the viewfinder.

But according to some reports on Twitter, QR codes in the U.S. are about to get a second chance, because the first iOS 11 beta has the ability to read QR codes via the native camera app.
