About this app

Looking for a QR code scanner you can trust? QRSentry is more than a scanner — it checks every QR link for danger the moment you scan, protecting you from phishing and malware sites. Free, with no ads.

QR code scams ("quishing") are rising fast: fake QR codes on cafe tables, parking meters and posters, and phishing links hidden in text messages. Check it with QRSentry before you tap.

■ Why QRSentry?

• Instant safety rating (SAFE / SUSPICIOUS / DANGEROUS / UNKNOWN)
Every scan gets a 4-level threat assessment. Dangerous links are flagged before you open them, stopping phishing before it happens.

Backed by two of the largest global threat-intelligence feeds, updated daily. Known malicious URLs are blocked immediately.

• Dual analysis engine (server + on-device)
Firebase server-side analysis plus on-device heuristics — basic protection even when you are offline.

■ Features

URL, Wi-Fi, Contact (vCard), Email, SMS, Phone, Location, Calendar Event, OTP, Crypto, Deep Link, Text and more — the right action for every code.
