Groupboard

Groupboard is a free collaborative whiteboard (drawing board), allowing you to draw and chat in real time with other people anywhere on the internet, even with users using a web browser or an iPhone/iPad. Use it for online tutoring, collaborative design, or just for fun!

Simple to use - simply start the app and then draw on the screen by dragging your finger. Use two fingers (pinch gesture) to zoom in or out and scroll. Click the Connect tab to connect with other people.

Features include the ability to change colors, shapes, line width, and upload photos which you can then draw on. Log in as administrator for the ability to ban users and delete pictures.

When you first launch the app it will automatically create your own free Groupboard which allows you to connect to 5 other people. 15- and 50-user Groupboards are also available, starting at $9.99/month. Groupboard Designer provides a more advanced whiteboard with features such as infinite whiteboard size, multiple pages and the ability to upload documents, starting at $19.99/month. Once you have set up your own Groupboard you can access it from a web browser by clicking on a link, or from an iPhone/iPod/iPad/Android device using the app. You can also embed your Groupboard in your own web page if you wish. Note that the free boards may include adverts.
