I had a lot of fun while I was coding this App (the original version was done more than a year ago). Astrophysics, astronomy and science in general have always fascinated me and if you take a look at my Kindle or my bookshelf, you'll find a lot of Brian Greene stuff there.
Of course, the app is not meant to be any sort of a scientific tool, so don't count on it to do the calculations for your PhD thesis (just kidding, obviously).
Still, I hope that you'll have fun messing with the Schwarzschild radius and will enjoy the comparisons with some familiar everyday objects.
I've also submitted this version to Amazon Appstore and I expect to be approved (or oh, no... rejected!) sometime next week. Will keep you updated.
Take it from Android Market:
