Conspire Viewer is a free app for connecting to and watching Conspire whiteboard sessions. To participate in a whiteboard session, you need the full version of Conspire, available on the App Store.
Conspire is the world's best collaborative whiteboard app. It creates a whiteboard session that you can share across your local network or the internet, allowing you to easily sketch out ideas with remote coworkers, freelance clients or just about anyone, just as you would if you were all standing around a real whiteboard.
