LensFlow Scanner

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 — documents, whiteboards, and business cards — 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 — the words are embedded under the image, so you can find, select, and copy text in any PDF reader.

SCAN
• Continuous multi-page capture with automatic edge detection
• Automatic perspective correction as you shoot
• Append new pages to any existing document at any time

EDIT — ALWAYS NON-DESTRUCTIVE
• Four-corner perspective crop with draggable handles
• Rotate pages in 90° steps
• Five filters: Original, Color, Grayscale, Black & White, and Whiteboard
• Every edit re-renders from the original capture, so nothing is ever lost — reset any page back to its original scan
• Reorder pages by drag and drop, delete pages, rename projects

RECOGNIZE
• On-device OCR powered by Apple Vision — no server, no upload
• Automatic language detection
• Text position is preserved, so PDF search highlights land exactly on the right words in the page image

SMALL, PRINT-READY PDFs
• Every page is exported as a standard A4-size page — no more giant pixel-sized pages in viewers or on the printer
• Images are resized and optimised automatically (about 200 DPI), so a typical document is a few hundred KB per page: easy to email, sharp to read
• Your original scans stay at full resolution inside LensFlow

SHARE
• Export any document as a searchable PDF
• Select multiple documents on the home screen and share all their PDFs at once
• Select individual pages inside a document and share just those pages as one PDF
• Send anywhere iOS can share: Mail, AirDrop, Messages, Files, and more

PRIVATE BY DESIGN
• Everything stays on your iPhone — scans, text recognition, and PDFs never leave your device
• No account, no sign-in, no ads, no tracking, no analytics
• The camera is used only while you are scanning

LensFlow is built natively with SwiftUI and Apple Vision for iOS 17 and later, with a clean, focused interface.

Scan it once. Find it forever.
