ScanShield: Safe QR Scanner

ScanShield is a QR code and barcode scanner that checks what a code actually does before you open it — so you're never caught off guard by a malicious link, fake login page, or scam WiFi network hidden behind a scan.

Most scanner apps open a link the instant you scan it. ScanShield pauses first and shows you exactly what's inside: the full URL, the domain, whether it's HTTPS, and a safety score with the specific reasons behind it — so you decide whether it's worth opening.

Why ScanShield

Know before you open — every scan gets a safety score (0–100) based on HTTPS status, known URL shorteners, raw IP-address links, unusually long URLs, and phishing-style keywords like "verify," "login," or "wallet." Works completely offline — all safety analysis runs on your device, nothing you scan is ever sent to a server. Handles every common QR type — websites, WiFi networks, contact cards (vCard), phone numbers, SMS, email, calendar events, and plain text. Connect to WiFi directly from a QR code, save a contact from a business card, or call a number — all with one tap after you've seen what it does.

More than a scanner

Batch scan mode, a QR code generator (create and share your own codes), local searchable scan history with favorites, and one-tap safety report sharing.
