OffLens is a fully offline OCR app built on Apple’s VisionKit. Capture or pick photos, draw a precise crop, and recognize text in multiple languages without sending any data to servers.

Key features: · Offline by design: No uploads, no tracking, no ads. · Precise crop first: Drag corners or edges to target exactly what you need. · Multi-language OCR: Recognize text across many languages; auto-detect supported. · Proofread with highlights: See bounding boxes over the original image to verify accuracy. · Editable results: Review recognized text in a clean editor and copy with one tap. · History on-device: Keep up to 100 entries locally; view, edit, or delete anytime. · Camera and gallery: Snap a photo or import from your library; optional save-back after cropping. · Share and export: Copy lines or full results; share with friends. · Privacy-first: No analytics, no remote processing—everything runs locally.

QR Previewer

**QR Previewer** helps you check a QR destination before you open it. Instead of launching a website immediately, QR Previewer shows where the QR code leads first, so you can decide what to do next. **Features** * Preview the destination before opening * View a readable URL and domain details * Review local risk signals such as HTTP links, short links, IP-based hosts, and heavy tracking parameters * Get a cleaner link suggestion when removable tracking parameters are detected * Choose how to continue: open in Safari, use the in-app browser, or copy the link * Revisit your most recent scans on this device **Why use QR Previewer** QR menus, event links, and shared codes often open too quickly. QR Previewer adds a simple review step, making it easier to inspect unfamiliar destinations before visiting them. **Important** QR Previewer provides local heuristic guidance only. It does not guarantee safety and is not a malware scanner or phishing blocker. **Privacy** Scan results are processed on device in the current version. QR Previewer itself does not upload your scanned URLs or scan history.
