The Doceri interactive whiteboard and screencast recorder app, like the Splashtop app I reviewed earlier, is useful to anyone wishing to remotely control a projected image from a connected computer, make screen annotations on what is displayed (you can make the annotations on a displayed image or a whiteboard), and send your creation for others to see. The thing I liked the most about using Doceri is the ease with which recorded audio and screen annotations can be made and the ability to send/post the finished product to a LMS or similar system for students to access. This app can save you the expense associated with costly classroom whiteboards and the controls in the app are easy to navigate.
