Make sure you are using Salesforce Classic to complete this module and that you are signed in to the correct developer edition org. You should be able to see the application by selecting it from the menu on the top-right corner of your window.
I got here by clicking the "Launch" button next to "Trailhead Playground 1" on a Hands-on Challenge.
