GA Cacher is an Android app developed by mtrax for Geocaching enthusiasts who support the Geocaching Australia site. It allows you to load and display details of GCA geocaches while you're out in the field, including logs and location on Google maps.

One of the best features of GA Cacher is the ability to display nearby geocaches from Geocaching Australia, including Trig, movable, virtuals, and more. You can also filter by Geocache type, load only Traditional, Multi, and other types. The app allows you to select the number of caches to load fromYou can easily navigate to the geocaches using Google maps and launch the app from GCA links email or URL links.

The app also lets you log Found/DNF from the details page and refresh Movable details. You can even log Movable Cache location with GPSr. Additionally, you can add photos to logs from the Android Gallery and show the history of the last logs to the GCA website. However, it's important to note that the app does not support Groundspeaks Geocaching lists at present and that GCA does not support this app, so any issues should be sent directly to the developer.
