This GPS tracker application is designed to be simple, efficient, and precise while also conserving device battery life. It operates entirely offline, meaning it does not depend on internet connectivity or integrated maps to function. A key feature is its ability to accurately determine the altitude above sea level, especially when the EGM96 altitude correction is activated in the settings, providing users with reliable elevation data. Users can record their trips, view the recorded routes through external viewers that support formats like KML, GPX, and TXT, and share their tracks easily using various sharing options.
One of the main advantages of this app is that it is completely free and open source, allowing anyone to access, modify, and contribute to its development. The app offers a modern, user-friendly interface with a dark theme that is energy-efficient, and it employs a tabbed layout to facilitate navigation. It supports continuous GPS data collection both in the foreground and background, with specific instructions to disable battery-saving features on Android 6+ devices to ensure consistent tracking performance. Users can add annotations mid-recording, visualize GPS data, and adjust altitude measurements manually or automatically using the NGA EGM96 Earth Geoid Model, which can be enabled for more accurate altitude readings.
The app is versatile and caters to various needs, such as trip logging, making precise measurements, geo-tagging photos, and sharing tracks with friends. It also supports collaboration with mapping projects like OpenStreetMap. Multiple units of measurement—Metric, Imperial, and Nautical—are available to suit user preferences. The app encourages community participation by inviting users to contribute translations via Crowdin, and it offers comprehensive FAQs to help troubleshoot common issues. Important notes highlight permissions required on newer Android versions and the necessity to disable battery optimizations for uninterrupted background operation. Additional resources, source code access, and license information are provided to foster transparency and community engagement.
