Geocachers use a wide variety of software in pursuing their sport. This includes programs for mapping, managing their waypoints, and other uses.
Geocaching Apps (with Mapping and Waypoint Management)
Groundspeak's Geocaching Apps for iPhone and Android
A free to use geocaching application for Windows Mobile Phones & PDAs. The application actually speaks, telling you where the cache is from your current position. Lots of good features: Loads GPX/LOC files, On Screen Compass & Nav, Built-in Cache Management etc.
A free, open source program for the Android platform.
A premium (paid) program for the Android platform. Neongeo uses the Geocaching Live API.
A free program that connects directly to Geocaching.com. Supports AppToDate to keep you always up to date.
CACH'EYE is a free personalised map service for geocachers. Each user can define the contents of his personal cachemap. Cache data are imported from Pocket Queries, from GPX- / LOC-Files or are exported from GSAK and visualised in an easy-to-use interactive map with 15 different basemaps. ToDo-Lists together with the print function provide a powerful tool for planning your caching routes.
ExpertGPS is a combination waypoint manager and mapping app. It can read and write waypoints, routes, and tracks to and from your GPSr. It can also read GPX and LOC files from Geocaching.com. It's main feature is the ability to download satellite and topo maps on the fly from the internet. Unlike a mapping app like Streets and Trips, you must be connected to the internet to download maps. ExpertGPS caches the maps it downloads, so you could pre-download an area of maps before going out caching. A handy feature is the ability to bring in "scanned maps." If you were holding an event at a park which has a large number of caches, you could load up a park map from the internet of scan it in from a brochure and superimpose the locations of all the caches. ExpertGPS is Windows-only and is shareware.
GeoBuddy is geocaching software that maps your geocaches over topo maps and aerial photos (for locations in the United States) and your own scanned maps (worldwide). GeoBuddy shows all of the geocaches in your GPX pocket query or LOC file, and lets you search and sort geocaches based on difficulty, distance from home (or any other point) or any other criteria. You can add geocaches to your personal "to-do list", send them to your GPS receiver, and print out maps to carry with you on the cache hunt. The built-in geocaching Web browser lets you view caches and log your finds when you return home. GeoBuddy is built on the ExpertGPS map engine. GeoBuddy runs on Windows XP and Vista. A fully-featured, free trial is available.
A handy program to have on a laptop, especially when doing paperless caching. You can load up all the area caches, plug in your GPSr and autoroute your way from cache to cache. The one big disadvantage is that it cannot directly import GPX or LOC files. You need to use a separate program to convert the waypoints to a CSV file. Streets and Trips also allows you to create custom icons for all your waypoints, so for example, you could load in all your caches by type and give different icons to the traditionals, multis, virtuals, etc. Streets and Trips is Windows-only, and can be found cheap at Sam's Club.
Free MS Windows software to create aerial photo or topo maps based on data from Microsoft's free msrmaps.com website.
Windows Mobile Geocaching Software for Phones/PDAs
Open Cache Manager
Open Cache Manager (OCM) is a free/open source geocache manager for Linux operating systems. This software allows users to import geocache listings from GPX or LOC file formats, add notes and/or waypoints to cache listings. and transfer geocaches to a GPSr. OCM has an extensive set of filters that can be applied in various combinations for more complex filtering than what can be achieved through pocket queries. It also features a map pane where cache icons and waypoints are displayed. OCM works with Geocaching.com, Terracaching.com, Navicaching.com and Open Caching sites.
