Turn your iPhone into a pocket document scanner: point the camera at any paper page and get a clean, auto-cropped multi-page PDF in seconds — then pull the words off the page, drop your signature on it, and send it without ever leaving the app. Most scanner apps stop at the capture. This one finishes the job entirely on your device: automatic page detection squares and straightens the paper, on-device text recognition turns every scan into words you can search, copy, and export, and your saved handwritten signature goes straight onto the page. No account, no upload, no internet connection at any step. WHAT YOU GET - Clean multi-page PDFs straight from the camera, with automatic page detection and perspective correction - Searchable, copyable text lifted off any scan by on-device recognition, page by page, exported as TXT or PDF - Your handwritten signature drawn once, saved, then placed on any page and written back into the document - A business card reader that pulls out name, email and phone, and a receipt reader for merchant, date, total and line items - A QR and barcode reader, plus converters that turn photos from your library or typed text into a PDF - A tidy library: folders, favorites, search, sorting, rename, page reorder, rotate and delete, then share or AirDrop as PDF PERFECT FOR - Freelancers and small businesses turning contracts and invoices into signed PDFs - Students digitizing handouts, notes, and printed chapters - Anyone filing receipts, IDs, and paperwork for taxes or personal records - Remote workers who need to scan, sign, and send a document from their phone WHY NOT JUST PHOTOGRAPH THE PAPER? A camera photo is crooked, shadowed, oversized, and buried in your camera roll. This app squares the page, builds a proper multi-page PDF, makes the words searchable, lets you sign it, and hands you one file you can actually email. PRIVACY No account, no sign-up, no cloud upload, no tracking. Every scan, every text recognition pass, and every PDF is created and stored locally on your device, and the app works with no internet connection at all. FULL ACCESS The free version gives you 5 scans per day plus the QR and barcode reader and the photo-to-PDF and text-to-PDF converters. Full Access removes the daily scan limit and unlocks text extraction from your scans, saved signatures and document signing, and the business card and receipt readers. Choose a weekly plan, a yearly plan, or a one-time lifetime purchase you pay once and keep forever. Scan your first page in the next 30 seconds — open the app and tap Scan.
