TrueQR is the QR scanner that remembers and tells the truth. Your phone's camera scans a code, opens the link, and forgets it ever happened. TrueQR keeps a private, searchable log of every scan — and tells you what's really inside a code before you open it. EVERY SCAN, REMEMBERED • Unlimited history of everything you scan — free • Search, filter, favorite, and add notes • Scan live with the camera, or from any saved image or screenshot • Reads QR codes and retail barcodes: EAN, UPC, Code 128, Code 39, ITF-14, Data Matrix, Aztec, PDF417 — copy a product number in one tap SAFETY BEFORE YOU TAP QR phishing ("quishing") is everywhere — fake parking-meter stickers, menus, posters. TrueQR checks every code offline, instantly: • Flags look-alike and disguised domains • Warns on URL shorteners that hide the real destination • Warns on insecure links and raw IP addresses Nothing is ever blocked — you stay in control, informed. PAYMENT QR X-RAY Point TrueQR at a payment code (PayNow, SGQR, LankaQR, UPI, PromptPay) and see who you're actually paying — merchant, amount, and an integrity check — before you open your banking app. PRIVATE BY DESIGN • No ads. No accounts. No analytics. No tracking. • Scanning and analysis run entirely on your phone — even in airplane mode • Your scans never leave your device ALSO INCLUDED • QR generator for links, text, Wi-Fi, and contacts — free forever • Instant-open mode: safe scans open immediately; suspicious ones always stop for review TRUEQR PRO — ONE-TIME PURCHASE, NO SUBSCRIPTION • CSV / JSON export of your history • Full payment field tree (every EMVCo tag, decoded) Scanning, analysis, safety checks, and unlimited history are free forever.
