c:geo ~ Let's find some geocaches!
c:geo is an open source, full-featured, always ready-to-go client for geocaching.com (unofficial) and offers basic support for other geocaching platforms (like Opencaching). It does not require a web browser or exports - just download and start right away.
Open Source — Although this app doesn't use the official geocaching.com API, it's still good for the casual geocacher.
