Most scanner apps are where documents go to be forgotten. scanAll reads every page you scan — right on your iPhone — so you can find any document by what's written inside it. Search "687,500" and the invoice comes back, with the amount highlighted on the page. And every feature is free, forever. No paywall, no subscription, no in-app purchase, no watermark, no scan limit, no account. FIND ANYTHING • Full-text search across your whole library — search by the words inside your scans, not just the filename • Matching text is highlighted right on the page, so you see where it is • Select and copy any recognized text — invoice numbers, amounts, addresses • Documents are named automatically from their contents CAPTURE • Camera scanning with automatic edge detection and perspective correction • Multi-page documents in a single scan • Or import existing photos from your library • Import PDFs and images from the Files app — every page is read so you can search it like a scan • Text recognition runs in the background — your scan appears instantly EDIT • Automatic and manual crop • Perspective correction and rotation • Four filters, each previewed on your actual page: Original, Grayscale, High-Contrast Mono, and Color • Delete, reorder, or re-capture individual pages • Redact — text under a blacked-out area is left out of search, copying and exports (document names you set yourself stay as they are) • Add pen, highlighter, signatures, stamps and text boxes — signatures are saved on your device for reuse • Correct recognized text — fix or delete lines, and search, copying, searchable PDF and Hangul, Word, Excel and text exports use your corrected text (the scan image is unchanged) EXPORT • PDF • Searchable PDF — the text layer is embedded, so it stays searchable everywhere • JPEG and PNG • Hangul (HWPX), Word (DOCX), Excel (XLSX) and plain text — text and tables carried over so you can edit them • Review and fix tables before exporting • Preview the files you made before sending them (formats that support preview) • Attach exported files to a new email in one tap (the share sheet opens if Mail isn't set up), or save to a Files folder (iCloud Drive, Google Drive and more) in one step • Quality options for PDF, images, and documents that include scan images ON-DEVICE & PRIVATE • Text recognition (Korean and English) runs entirely on your iPhone • No account, no sign-in — documents are stored on your device, not in a cloud • The app uploads nothing itself — files go out by email or to a drive only when you choose • Nothing is tracked or collected • Scanning, recognition, editing and conversion work in airplane mode (only email and drive transfers need a network) • Usage counts stay on your device and are never sent anywhere Free. Private. And your scans are finally findable.
