I just migrated from an iPad to a Nexus 7. One app that I used frequently was Jot. Basically it was a simple drawing app that allowed people to watch what I was drawing in real time on a webpage.
Is there an app like this for android?
To the date, No
The best you can get is to share your whiteboard through Wi-Fi. Go to goolge play store and search for whiteboard apps. You will find a plenty of great apps.
Hope this helps.
We created an app that allows you draw + chat with multiple users in real-time.
It's also a social network so can add friends, upload stuff, view a newsfeed etc.
