TurboScan
Evernote Scannable app (iOS)
TinyScanner Pro turns Android and iOS devices into portable document scanners. It scans everything as images or PDFs.
Adobe Scan (for Android and iOS) captures pictures, documents, notes, receipts, etc. and automatically sharpens them for clarity. With OCR, you can create a PDF that works with Adobe Acrobat Reader and similar products. It automatically stores every scan you capture on Adobe Document Cloud, so your scans are accessible from any phone, tablet, or computer.
