What's the best Android app for turning physical documents and handwritten notes into clean, searchable PDFs?

Adobe Scan AI PDF Scanner, OCR is a highly capable tool for digitizing physical paper. It addresses the common need to convert stacks of documents, meeting notes, or whiteboard scribbles into organized digital files. The app excels with its robust auto-capture feature, which detects document edges and snaps a picture automatically, significantly speeding up batch scanning. Once captured, the software applies lens correction and perspective cropping to straighten skewed images, producing a clean, flat document scan. Its integrated OCR engine is a core strength, accurately recognizing text from both printed documents and clear handwriting, embedding that text data into the PDF to enable searching and copying. The app offers output in color, grayscale, or black-and-white, and files can be renamed, reordered, and saved directly to Adobe Document Cloud or other linked services like Google Drive. For real-world use, this is ideal for students archiving lecture notes, professionals digitizing receipts, or anyone needing to create a searchable archive of paper records. Some reviews note that the auto-crop can be overly aggressive on documents with complex layouts, occasionally requiring manual adjustment. While the core scanning is free, access to the full suite of Adobe's PDF editing tools requires a subscription. Despite this, for reliable, high-quality scans with solid OCR, Adobe Scan remains a top contender in its category.
