Create your own videos
With TouchCast you can create your own Web casts with onscreen content your audience can touch to interact with.
You can explore featured TouchCasts to see what other users are making. With the tool set in this app, I don't think it's quite reached its full potential.
Get tips from the pros
If you go to the TouchFeed, you can find tips and tricks from the developers of the app.
Watch a channel, or create one
Check out the featured channels to look at all the videos from individual TouchCasters.
Manage your projects
The My Projects button shows you all the videos you've worked on. You can also save them in the middle of a project and come back later to finish up.
Video apps are vApps
The people at TouchCast use the word vApps to describe video apps. I'm not sure if it rolls off the tongue, but these things are very useful for bringing interactive content into your videos.
