Ever need to scan a document but don't have a scanner, so you take a picture and send it? It might work, in a pinch, but it isn't clear, there might be a glare, and you certainly can't edit it. The next time you need to send a receipt, a school permission form, class notes or notes on a white board, a time-card or mileage report...use Adobe Scan. A free app that uses your phone's camera to scan documents and convert them to a pdf. It also has OCR (optical character recognition) which means the app recognizes letters and words and creates an editable document.
