RealtimeBoard is an online whiteboard where you collaborate freely and visually on your business processes or everyday life. It's unlimited — you can use it to draw, make sticky notes, write text, upload PDF files, even from Google Drive. Invite your friends and colleagues to work together, discuss in mini-chats. All the changes are displayed and saved in real time for every participant.

The app is available right now. Sign up at realtimeboard.com and enjoy!
