QR Guard - Scan QR Codes

Scan QR codes and inspect their contents before opening links

On the App Store iPhone, iPad Free

QR Guard lets you inspect the contents of a QR code before opening a link or taking another action. It shows the raw content, recognises common types of information and warns about potential risks in links, such as look-alike domains and insecure connections. You can optionally check links through VirusTotal using your own API key. QR Guard is free, with no ads or tracking, but it cannot detect every scam or security threat.
