QR Image Scanner at Mac App Store analyse

QR Image Scanner lets you scan QR codes from: - your camera roll - a saved image - a webpage - an email - a pdf - a screenshot - basically anywhere on your device’s screen PROS - free - no ads - no tracking - integrated with share sheet (use from Photos, Screenshots, and other apps) CONS - only QR codes with URLs supported (for now) WHY? In iOS 11 Apple added the ability to scan QR codes from the Camera - just point to scan. There’s even a slick new QR Code Reader for Control Center in iOS 13. But if you want to scan a QR code from your screen (saved image, webpage, email) you need another app. 
QR Image Scanner fills this gap until Apple finally adds this feature.
