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.

Now, the Scanner Pro team is looking for a iOS Engineering Lead to help us deliver the best-in-class product to people all around the world.
