LensFlow turns your iPhone into a fast, private document scanner that produces truly searchable PDFs. USED MICROSOFT LENS? Microsoft retired the Lens app in early 2026. LensFlow gives you the same scan-to-searchable-PDF workflow ā documents, whiteboards, and business cards ā with your files kept on your device, no account, and no cloud required. Point your camera at any page and LensFlow captures it with automatic edge detection and perspective correction. Text recognition runs entirely on your device, and every export is a real searchable PDF ā the words are embedded under the image, so you can find, select, and copy text in any PDF reader.
