About this app

📄 Crisp Scan turns your phone into a proper document scanner. Point it at a page: it finds the edges, straightens the perspective, lifts the shadows and glare, and gives you a sharp, readable PDF.

🔒 Your scans stay on your phone. No account, no sync, no upload unless you ask for one. No watermark, no page limits.

📸 SCANNING THAT GETS IT RIGHT
• Live edge detection, auto-capture, and a blur and motion check
• Perspective correction and auto-deskew: a page shot at an angle comes out square
• Shadow and glare removal: a page under one lamp comes out evenly white
• Filters: Original, Color, Grayscale, Black & White — coloured print keeps its color
• 🪪 ID mode: both sides of a license or ID card on one A4 page — free
• 📖 Book mode splits a spread into two flat pages, 🖍 Whiteboard mode cleans up marker
• Import photos and PDFs from your gallery, files or the share sheet

📂 YOUR LIBRARY
• Folders, tags, rename, move, multi-select
• Search by name, and search the words inside your scans
• Tablet and foldable layouts put the list and the document side by side

🔧 PDF TOOLS THAT WORK ON THE REAL PDF
• Merge, split, reorder, rotate
• Compress with a preset, a size slider or a target size; page size Auto, A4 or Letter
• Print, share, open elsewhere, save as a new PDF
• Imported PDFs keep their text, forms and vector graphics

🔤 READING TEXT
• Latin, Devanagari, Chinese, Japanese and Korean through Google Play services
• 34 more packs on demand: Tamil, Telugu, Kannada, Malayalam, Bengali, Gujarati, Urdu, Arabic, Hebrew, Russian, Greek, Thai and more
• Select and copy text straight off the page
• Export a searchable PDF with an invisible text layer, so any reader finds it
• Export plain text, Word, Markdown, or a page's tables as an Excel workbook

🧠 IT READS WHAT THE DOCUMENT SAYS
• Names a scan after what it is: "FreshMart Supermarket Receipt Sep 2026", and tags it
• 🧾 Pulls the shop, date, total and tax off a receipt; a folder of them to CSV or Excel
• 📇 Reads a business card and hands it to your contacts app
• Reads an ID's number, name and date of birth — and keeps it on the phone
• Smart folders are rules, not places: every FreshMart receipt since April

✍️ SIGN, MARK UP, FILL IN
• Sign with a signature you drew, typed or photographed off paper
• Pen, highlighter, arrows, shapes and text boxes
• Fill in a PDF form's real fields, and it stays a form
• Watermarks and page numbers, in any script

🛡 PRIVATE BY DEFAULT
• App lock with a PIN or your fingerprint
• An encrypted vault with a PIN of its own: AES-256, sealed by your phone's keystore, so the files are useless on any other device
• True redaction: the pixels and the text really go, not a black box drawn over them
• Password-protected PDFs, AES-256
• Cloud backup is off; phone-to-phone transfer carries your documents to a new phone

📤 SEND IT WHERE YOU WANT
• 📶 Hand a document to another device over your own Wi-Fi with a QR code: no cable, no cloud
• ☁️ Upload to your own WebDAV or Nextcloud server, or any folder your phone can reach — Drive, Dropbox and OneDrive included
• Auto-upload a folder, so a scan goes where it belongs by itself

⚡ QUICK WAYS IN
• Quick settings tile, home screen widget, "Scan to…" shortcuts for your busiest folders
• Batch actions: read many documents' text, rename by rule, export them all
