Apps that that are more complex require an iterative development process.  This involves:

1. Plan what to add to the script, or what to adjust to make it work better or fix an error
2. Write code or change existing code
3. Test to make sure it runs as planned while checking for errors
4. Report errors, suggestions for improvement, etc.  Then, it’s back to step 1.

In the previous activity, you completed two iterations of the steps.  In this activity, we’ll do two more iterations, one to tune the tilt compass so that it does a better job of pointing down.  Then, we’ll ask the AI to improve the script.
