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.

QR codes can house a whole lot of data, from the URL of a webpage or service, to where to directly download an app. Here's how to scan them.

Your Android or iPhone can probably already scan QR codes. Here's how to do it no matter what phone you have.
