Why is the Cozmo app Required?
The Cozmo app is used to play games, teach Cozmo new behaviors, help him meet new people, and even control him. Once Cozmo is connected to his app, you can set aside your device and let Cozmo roam around on his own. It’s fun to just hang out with him.
When you close or background the app, Cozmo will go to sleep, and eventually disconnect from your device.
