iPhone

Photograph or pick pages, straighten and enhance them, arrange them and export one searchable PDF. Everything stays on your phone. Scan & Stack turns photographed or picked pages into one clean, searchable PDF, entirely on your iPhone. CAPTURE Use the built-in document scanner for multi-page captures, or pick existing photos and files. Every imported page is automatically detected, straightened and cropped if it looks like a sheet of paper; you can always fine-tune or redo the four corners yourself, or switch to a plain rectangular crop for photos that are not documents. ENHANCE Each page gets an automatic "Document" cleanup: the paper is balanced towards white, contrast is lifted and shadows are brightened. Switch any page to Original, Color, Grayscale or Black & White instead, with a live preview before you export. ARRANGE Reorder pages by dragging them, rotate, duplicate or delete any page, and choose how many images share a PDF page: 1, 2, 4 or 6, in a matching layout. Page format is A4 or US Letter. SEARCHABLE TEXT On-device text recognition (Apple's Vision framework, German/English/French/Spanish) adds an invisible text layer to the PDF, so the result is searchable in Preview, Spotlight and other PDF readers. No text ever leaves your phone for this. LOCAL STORAGE Finished PDFs are saved locally on your iPhone, visible in the Files app under "On My iPhone". Search your own library by title or by the recognized text. PRIVACY BY DESIGN Scan & Stack has no account, no server and no analytics. Scanning, straightening, enhancement, text recognition and PDF creation all run locally with Apple's on-device frameworks (VisionKit, Vision, Core Image, PDFKit). Nothing is uploaded anywhere. TRY IT FREE The first three PDF exports are free, with a small watermark. After that, Scan & Stack Pro removes the watermark and unlocks unlimited exports — monthly, yearly, or a one-time purchase for lifetime access, with no subscription at all. The subscription renews automatically until cancelled in your Apple ID settings; the one-time purchase is a single payment with no renewal. Price and terms are shown by the App Store.
