Global Schooner is an app for Prairie Schooner Magazine showing where their authors are located around the world. I like the subdued icons and the corner based navigation.
Pray 2x7:14 is an app by Rueben Thiessen and seems to be a bit of a social network for prayer. I like his use of great circles, very nice visual.
Both of these are great examples of what you can do with the WhirlyGlobe-Maply Component without too much trouble. These are far removed from the iPad melting insanity I make my living at and are just the sort of specialty apps I love to see using the toolkit.
I'm way behind on apps, so feel free to bug me if I haven't posted yours yet.
