Because we don't have time for a full round of crits this Thursday, I'm asking you to do a bit of user research with your apps for Thursday.
Find a friend, a relative, or grab someone in the hallway, explain the basic idea of your app, then have them start using your prototype (software or paper). Video the result using one of your phones.
Put the result somewhere online (e.g. DropBox), then play it for the class on Thursday. We'll spend about 10 minutes for each group.
