Ask HN: What app should I build using App Inventor?

I don't have access to App Inventor yet, but hopefully I'll get it soon. If I do, I'd like to try to use it to build an app that someone wants.

My only programming experience is 1. Intro to CS class in 2003 2. Currently learning Python using MIT OCW 6.00 Introduction to Computer Science and Programming

I'm interested in recommendations both from those who think App Inventor is a great idea and those who think it is unlikely to lead to anything of value. Thank you.
