Record the inputs and outputs of the Pet Chooser app.

### Story Creator
Record the inputs and outputs of the Story Creator app.

### Other Inputs
Besides inputs that comes directly from the user, brainstorm other ways an app might get the information that it needs. Take inspiration from the improved Pet App and apps you use in your daily life. Apps can get information from phone sensors and the Internet.

Record specific examples of information that an app can get that does not come directly from the user.

### Your App Idea
Think of a new app idea. It must include multiple sources of input. Describe what it does and record its inputs and outputs.
