QR Square is a very simple and easy to use QR code scanner app for iPhone. It also has the capability to read standard barcodes. With QR Square, scanning a QR code or barcode is as easy as pointing your camera at the code.

Once scanned, QR Square automatically saves the code and opens the appropriate application that can handle the code content. For example, if the QR code contains a website URL, QR Square will take you to the website. If the code contains plain text, you can view it immediately or search it with Google. Geolocation codes will display a map with a location marker. If the QR code contains a Facebook URL and you have the Facebook app installed, QR Square will open the app for you.

QR Square is an all-in-one scanner that does not require an internet connection for scanning. It also supports flashlight usage for scanning in low-light environments. The app saves your scan history and allows you to decode codes from saved images. Additionally, you can instantly share barcodes with others. If you are using iOS 11 or above, QR Square even allows you to log on to WiFi networks with just one snap.
