About

DetectQR

Read full description

QR codes often contain multiple redirects that can lead to dangerous websites โ€“ a security risk that has never been addressed so effectively before. Whether in everyday life, while shopping, or on the go, DetectQR gives you the confidence to scan any QR code without worry. Unlike conventional QR code scanners that only display the visible link, DetectQR analyzes the complete redirect chain and resolves every QR code to its final destination link, allowing you to see exactly where it leads before opening it. Every scan is processed in a secure cloud environment, keeping your device safe. DetectQR goes beyond resolving redirect chains. An integrated security check detects potentially dangerous websites and protects you from phishing, malware, and other online threats that might be hidden behind seemingly harmless QR codes. You can also check manually entered links to detect potential threats before visiting the website. Additionally, the Pro version features AI-powered security analysis, real-time traffic insights (including a domain-age check and visitor data from the previous month), as well as a screenshot preview of the website. The intuitive user interface makes the app incredibly easy to use. Scan, detect, and browse safely โ€“ with DetectQR.
