Hey! I’ve been using the Scanner App from
scanner.biz. It turns your iPhone into a powerful mobile scanner, with Optical Character Recognition (OCR) and Handwriting Recognition to easily convert documents into PDFs or JPGs. You can also choose between automatic and manual capture modes, and the app has options for enhancing scans with edge detection and color correction. Plus, all your scans are stored locally on your device, and you can sync them with cloud services.
