TurboScan turns your iPhone into a multipe page scanner for documents, receipts, notes, whiteboards, and other texts. With Turboscan you can quickly scan your documents and store or email them as multiple PGF or JPEG files.I have found the following apps extremely useful (e.g. Student work samples, or a snapshot of the whiteboard) and, having shared them with my immediate colleagues. I thought them to be useful and time-saving.
