App Inventor Experiment - The Criteria

As I promised in last post behold the experiment's criteria:

• The app must be developed via Google's App Inventor
• It should use persistent storage to store and retrieve data
• It should display the stored data to the screen in some way
• It must have a real world use and cannot be a usual "hello world app"
• The interface must be considerably polished and not just thrown together

The criteria make for a pretty tough challenge for any developer, let alone somebody with no previous development experience and thinks if statements are what you use when deciding what cooking ingredient to use. So good luck to Maria, she's going to need it.
