IOS iPhone Simulator killing a running app

Problem:
Running my new app in the simulator and each time I start it up it defaults to the latest screen.
This is by design as it starts up where you  left off.  I need to give a demo and need to get it to start at their first screen.  How do I kill the session in memory?

Solution:
For iOS 7 & 8:

• shift+command+H twice to simulate the double tap of home button
• swipe your app's screenshot upward to close it
