Well, that's true, in the same way that my bicycle cost me less than my car.
If I've read your page right, your app takes your current coordinates, say N52.3 W1.2, and opens a browser window at this URL:
Code:
https://www.geocaching.com/seek/nearest.aspx?origin_lat=52.3&origin_long=-1.2
Is that all? If so, I'm guessing it's about 5 lines of code, excluding the UI.
Groundspeak's app does a little more than that, I believe.
