Geocaching Plus is an app that makes it really easy to go hunting for geocaches, listed on Opencaching.com service, with your Windows Phone device. Key features include the ability to search for caches, view nearby caches on a map, view cache listing and log details, save favourite caches and more.

Geocaching, for those that don't know, is an outdoors sporting activity / treasure hunt in which participant use a GPS to navigate to a given set of co-ordinates, in order to find a geocache (cache). The geocache is usually a container, inside which you'll find a number of items including a log book that you can sign with a date and name to record your visit. 

Opencaching.com is a Geocache web site that aims to be as open and free as possible, with no paid content. All the caches are published under an open source license. This contrasts with geocaching.com, which has the biggest list of caches on the web, but some features are only available to paid members. Geocaching.com has its own Windows Phone app, Geocaching Live, which we wrote about earlier this year.

Ultimately the existence, and difference between, the two sites, and the two apps, is partly a reflection of politics within the Geocaching community. Opencaching.com does not have anything like the number of geocaches in its database as Geoaching.com, but some may prefer the non-commercial philosophy that underpins the site.

Geocaching Plus isn't as fully featured as Geocaching Live, but it does get the job done, and it's good example of how a smartphone app can provide a superior experience to a website. The ability to easily look up and view cache information while on the move is invaluable, and adding it the location sensing abilities of a smartphone adds an extra layer of convenience.
