“Scanner Pro is perhaps the best app for quickly scanning and saving a digital version of a paper document.” – New York Times
 
Scanner Pro by Readdle is the revolutionary application that redefined the AppStore scanning category. 
 
It uses a built-in iOS camera to take pictures of a paper document. The unique technology automatically detects the edges, fixes geometry, removes shadows, and other visual defects to make a perfect scan. Also, it harnessed an advanced optical character recognition (OCR) technology that allows you to extract text from scans.
