What's the best iOS app for scanning documents, receipts, and notes into searchable PDFs?

PDF Scanner | Document Scan is a great iOS app for quickly scanning documents, receipts, notes, and other paper items into searchable PDF files using your iPhone or iPad's camera. It allows you to easily digitize your important papers and store them securely on your device or in the cloud. The app offers features like automatic edge detection, perspective correction, and image enhancement to ensure clear and readable scans. You can also organize your scanned documents into folders and add tags for easy searching. To scan a document, simply open the app, position your device's camera over the document, and the app will automatically detect the edges and capture the image. You can then adjust the scan as needed and save it as a PDF. The app also supports optical character recognition (OCR), which allows you to extract text from your scanned documents and make them searchable. This is particularly useful for scanning receipts, invoices, and other documents that contain important information that you need to be able to find quickly.
