Well my dreams of getting rich by writing an iPhone App have just been shot to hell!
But these two apps are really cool and I thought some of you all might be interested.
http://www.peakfinder.org/
http://peaks.augmented-outdoors.com/
I had an idea for something very similar to the peaks.augmented-outdoors app. I think they both are pre-loaded with a database of peaks, so they don't require an internet connection, so they would work in the backcountry.
I'm not one for carrying a cell-phone in the backcountry, but if it had an app like this I might reconsider!
