Scan anything on paper and turn it into a clean, professional PDF in seconds. Scan Studio is the scanner that lives in your pocket, ready whenever a receipt, contract, or handwritten note needs to become a proper document. Here is the problem with paper: it gets lost, it fades, and it is never with you when you need it. Scan Studio fixes that. Point your camera at a page and the app finds the edges, straightens the angle, removes shadows, and gives you a sharp scan that looks like it came from an office scanner. Keep snapping and a 20 page contract becomes one tidy PDF, ready to email before you have even left the room. WHY YOU WILL WANT IT ON YOUR HOME SCREEN SAVE TIME EVERY DAY Scanning takes seconds, not minutes. Capture page after page without stopping, so long documents are no longer a chore. Import photos or existing PDFs and work with everything in one place. It works just as well on iPad as on iPhone, so you can scan with whichever device is in your hand. LOOK PROFESSIONAL Smart filters powered by machine learning clean up your scans, sharpen the text, and remove artifacts, so the PDF you send to a client or a landlord looks polished. Set page sizes, reorder pages, and export exactly what you want. ONE APP FOR ALL YOUR PDF JOBS Stop juggling a different app for every little task. Merge several files into one, split a long PDF into parts, compress a heavy document so it actually sends, add a watermark, or lock sensitive files behind a password. From the moment you point your camera at a page to the moment the finished PDF lands in someone's inbox, everything happens in one place. KEEP EVERYTHING ORGANIZED AND PRIVATE Store your documents in folders in the built in library, so the receipt from last March takes seconds to find, not an afternoon. Back everything up privately with iCloud, using your own Apple account and no third party servers. Your documents stay yours, and only you can access them. WHAT PEOPLE SCAN WITH SCAN STUDIO Receipts and expenses for tax season. Contracts, agreements, invoices, and bills. ID cards and passports. Homework, lecture notes, and whole textbook chapters. Recipes, warranties, whiteboards after a meeting, and the kids' drawings you cannot bear to throw away. If it fits in front of your camera, it fits in Scan Studio.

Verdict
One Scan and Document Scanner both sit at 4.7 stars, but that hides the real split: 90% of Document Scanner's written reviews are positive against 26% of One Scan's. Document Scanner also leads on update cadence (every 2 weeks vs every 2 months) and iOS requirement (18.0 vs 26.0). One Scan's advantage is ratings volume (12K vs 556). On price, rating, ads and in-app purchases there is nothing between them.
