PDFpen Scan+ is similar to Readdle’s Scanner Pro, which allows an iOS device's camera to be used as a portable scanner. Snapped documents can be cropped (automatic or manual), enhanced, and saved as color, black-and-white, or grayscale PDF files, and then shared in a variety of ways. Smile has gone the extra mile by adding optical character recognition (OCR), which is an optional step after the file is saved. This task takes several minutes to perform, only to produce unformatted text that has to be copied and pasted into another app. We found the OCR results to be wildly inaccurate in most cases, however.
