About

iScanDocs

Features
Read full description

iScanDocs is a document scanning and conversion app built for professionals who need reliable, private, structured document handling — without the risk exposure that comes with AI-powered alternatives. Automatic deskewing, on-device OCR, clean PDFs — entirely on your iPhone. Nothing leaves your phone. No account. No server. No AI anywhere in the pipeline. SCAN Point your camera at any document. VisionKit finds the edges and corrects the perspective automatically — the same on-device geometry Apple uses in Notes. Pages come out straight without asking anyone's server for help. TEXT EXTRACTION Every scan produces a companion .txt file alongside the PDF. Searchable, copy-pasteable, shareable. Extracted entirely on-device via Apple's Vision framework. RAPIDSCAN Tap the bolt. Scan. Done. No naming screen, no folder picker — captures instantly, lands in Unsorted. Move it to a folder when you're ready. IMPORT FROM PHOTOS Have a photo of a document already? Import it directly from your camera roll — same PDF output, same OCR, same deal. ORGANIZE Create folders, name them what you want. Move documents between folders. Long-hold any empty folder to delete it. Your files are real files in real folders — visible in the iOS Files app, moveable, AirDroppable, yours. PRIVACY iScanDocs has no server, no analytics, no crash reporter, no account. If you don't make a purchase, it makes zero network requests of any kind. Documents are stored locally in your iPhone's Documents directory and nowhere else. We have no access to any of it. For legal work product, medical records, financial documents, or anything else you'd rather not explain to a cloud service — this is the scanner.
