Scan-Scan is a barcode and QR scanner that does exactly one thing, exactly the way it should. Point your camera at a code. See what's inside it. Copy it, share it, or act on it. That's the whole app. **WHAT YOU GET** • A full-bleed camera that recognizes QR, Data Matrix, Aztec, PDF417, EAN, UPC, Code 39, Code 128, ITF, Codabar, GS1 DataBar — every common 1D and 2D symbology, all enabled by default. • The raw decoded string, in monospaced text, selectable, never truncated, never "interpreted" into something you didn't ask for. • Smart actions only when they fit: open a URL, join a Wi-Fi network, add a contact, drop a pin in Maps, start a call. If it's plain text, you get plain text. • A persistent history of every code you've ever scanned, grouped by day, searchable, filterable by type. Tap any past scan to see the exact data again. • Import barcodes from photos in your library. • Torch toggle for low light. **WHAT YOU DON'T GET** • No ads. Not banner ads, not "sponsored" results, not interstitials. • No accounts. No sign-up, no sign-in, no email, ever. • No cloud. Your scan history lives on your device and only your device. • No tracking. No analytics SDKs, no telemetry, no third-party packages of any kind. • No "product lookups" that pipe every UPC you scan to a vendor database. • No subscription. No "Pro" tier. No paywalled features. • No barcode generation, no batch inventory mode, no CRM integration — those apps already exist. This isn't one of them. **HOW IT'S BUILT** 100% native Swift and SwiftUI. Apple's VisionKit for scanning. SwiftData for history. Zero third-party dependencies. The entire app works offline; the only network traffic is when you tap a link and iOS hands it to Safari. **WHO IT'S FOR** People who scan a code and want to know what's actually in it — developers debugging a QR payload, anyone joining a Wi-Fi network at a friend's place, someone who'd rather not install 40 MB of advertising SDKs to read a sticker. Open the app. Scan. Done.
