A couple of weeks ago I downloaded the Scanner Pro iPhone app from Readdle. I played around with it at my desk and then kicked myself for spending $6.99 on an app I probably wouldn't use very much. The app creates pdf documents using the iPhone camera and then gives you multiple options for sharing those documents including email, Dropbox, Google Docs, iDisk, Evernote, etc. However, I was comparing it to a Xerox scanner in the office and that wasn't a fair fight.
Recently my wife handed me some documents that she wanted me to take to the office, scan and email back to her. Instead I pulled out my iPhone, snapped four pictures, created two pdf documents and emailed them back to her, all in about 3 minutes. The quality is not great, but it is OK. CPA's and other professionals might find Scanner Pro invaluable in use cases where document information capture rather than document duplication is the goal. For instance, I had lunch with a client this week where he asked me to review his last pay stub for withholding sufficiency. Rather than bring the stub back with me I could have created a pdf on the spot and let him retain the original.
I would like to see how Scanner Pro works with the new iPhone's 5 megapixel camera. If anyone wants to try it out and link to a review in the comments I would be greatful.
