Genius Scan+

I often use my iPhone to take pictures of pages or documents. It is easier than writing notes, or bringing a scanner with me. The different between using the Camera app and Genius Scan+ is that Genius Scan+ will usually recognize the border of the document and adjusts the perspective to make the document flat, as if it was scanned, even if I took the picture at an angle. Even when it doesn’t get it right, it allows me to adjust the corners so I can make it better. You can export single pages as jpeg images, and multiple pages as PDFs. You can send to services like Dropbox, Google Docs and Evernote too.
