About

Tertiary Scanner

Features
Read full description

Scanner is a clean, fast, fully-offline document scanner. Point your camera at a page and it auto-detects the edges, corrects perspective, and crops for you — A4, Letter, receipts, business cards, notes, or whiteboards. Scan multiple pages into one document, then enhance each page with filters: Auto, White Document, Black & White, Denoise, Brighten, Sharpen Text, and Receipt mode. Export as a single- or multi-page PDF or as high-quality JPGs, and save straight to Photos, Files, or iCloud Drive. Built-in OCR recognises the text on every page so you can copy it, export it, and search your whole library by content. Share to AirDrop, Mail, Messages, WhatsApp, or print — all from the native iOS share sheet. Everything runs on-device: no account, no cloud, no tracking.
