Scan. Preview. Then decide.

$0.99 · Designed for iPad. Not verified for macOS.

Scan, preview, then decide. Multi-layer URL decoding reveals hidden redirects. Batch scan with auto-dedup. Home screen widget. No ads. On-device. Privacy first. CodeKnow — a professional scanner that shows you what's inside before you open it. This is not another "scan and jump" scanner. We believe you should see exactly what's inside a code before deciding whether to open it. [Our Philosophy] Scan first, preview, then act. Every successful scan brings up a preview panel — you see the raw content, parsed results, and security notes before choosing to copy, open, favorite, or dismiss. Links never open automatically. [Why You Need It] WeChat, Alipay, and the system camera all scan codes — but they jump straight to the destination, skipping the crucial "let me look first" step. Professional scanner apps exist, but they're often bloated with ads and features you don't need. CodeKnow focuses on one thing done right: showing you code content so you can decide safely. [Core Features] ■ Smart Recognition Supports QR codes and common barcodes (QR, EAN-13/8, UPC-A/E, Code 128/39, and more). Powered by iOS VisionKit for on-device recognition — works offline, even in basements and warehouses. ■ Preview Before Opening A preview panel appears after each scan, showing raw content and structured results. URLs display domain, path, and parameters; Wi-Fi shows network name and password; contacts show name and phone — all clearly laid out. Nothing opens until you confirm. ■ One-Tap URL Decoding (Flagship Feature) Many links are encoded in multiple layers, hiding the real destination behind unreadable %XX strings. CodeKnow automatically detects encoding depth and decodes layer by layer, revealing the true URL and parameters. When the decoded domain differs from what was displayed, you get a clear "Domain Changed" alert — a classic sign of phishing. All decoding happens locally. No URL is ever uploaded. ■ Batch Scanning Scan multiple codes continuously with automatic deduplication. Pause, resume, and review results anytime during the scan. Perfect for inventory counts, package tracking, and material checks. ■ History as Your Content Library Scan records are automatically saved to local history — searchable, filterable, favoritable, and deletable. The home screen dashboard shows stats and recent records, like managing your personal code content library. ■ Security Alerts Lightweight risk analysis for every URL: plain HTTP, short-link domains, oversized parameters, and encoded redirect patterns all trigger clear warnings before opening. High-risk links require a second confirmation. ■ Native Deep Actions Join Wi-Fi, make a call, or send an email — when content matches these types, CodeKnow hands it directly to the corresponding iOS system service. No manual copy-pasting needed. ■ Home Screen Widget Place a widget on your home screen for one-tap scanning or quick access to recent records — no need to open the app first. [Privacy First] · All recognition happens on-device. No scan content is uploaded by default. · History is stored locally and can be cleared at any time. · No ads. No pop-ups. No auto-renewal traps. · Any online capability requires your explicit permission and can be turned off. [Who It's For] · Marketing & Operations: Verify campaign QR codes and link parameters before launch. · Developers & QA: Debug QR parameters, short links, and deep links — copy raw content instantly. · Logistics & Warehousing: Scan product and package codes in bulk with traceable records. · Security-Conscious Users: Preview unknown QR codes before opening, avoiding phishing and malicious redirects. · Everyday Use: Look up previously scanned codes without rescanning. [Design Philosophy] Inspired by Linear and Notion — minimal, professional, and modern. Content breathes. Lines divide. Accent colors guide. The visual focus stays on what matters: the code content itself. CodeKnow — See clearly, then act.
