Scanning is a pain, especially when you're out of the office. Turboscan is a phone app I've been using and evangelizing for years. It makes scanning simple and fast. Using your phone camera, you can scan and compile a document, turn it into a PDF, and send it straight from your device. No more sending each page separately! No more waiting until you're in the office to sign and send a contract! Download it today!
