About
c:geo is a fully-featured, always-ready geocaching companion for Android devices, built entirely as an open-source project and offered completely free of charge. It supports multiple geocaching platforms at once, allowing users to consolidate their caching activity in a single app without juggling separate tools. The app features a live map that auto-updates to show nearby caches in real time, with support for both Google Maps and OpenStreetMap as map providers. Users can search for new or saved caches using advanced, multi-criteria search filters, and can create and manage custom waypoints to enhance their cache-hunting experience. Navigation is versatile — geocachers can use the built-in compass, the integrated map, or hand off navigation to external applications. Full offline support means caches, maps, and logs can be downloaded in advance, making it ideal for adventures in areas with limited connectivity. GPX import and export ensure compatibility with GPS devices and other geocaching tools. The app also supports trackables and GeoKrety, enabling users to track and log physical trackable items directly within the app. c:geo is community-driven, welcoming contributors to its codebase and relying on donations to cover server and infrastructure costs. It is available via Google Play, direct APK download, and F-Droid for users who prefer open-source app stores.
