GPX Analyzer is a command-line tool developed by the GPX Analyzer Project for analyzing GPX activity files. Its purpose is to process GPX tracks and extract a comprehensive set of activity metrics, making it relevant to the fitness and activity tracking category, particularly for users who work with data recorded from outdoor activities such as cycling, running, or hiking. The software analyzes GPX tracks and reports distance, elevation gain and loss, and speed, giving users a quantitative summary of their recorded activities. Beyond basic track statistics, GPX Analyzer includes stop detection, which allows periods of inactivity within a track to be identified automatically rather than being blended into overall figures. It also supports the analysis of biometrics recorded alongside the GPS data, including heart rate, power, cadence, and temperature, so activities captured with compatible sensors can be evaluated in greater depth. A notable feature of the tool is its altitude correction capability, which is performed via the SRTM digital elevation model; this addresses the common problem of inaccurate elevation readings in recorded GPX files by correcting altitude values against established elevation data. From a deployment perspective, GPX Analyzer is distributed as a self-contained Native AOT binary with no runtime dependency, meaning it can be run directly on a system without requiring a separate runtime environment to be installed first, which simplifies installation and use from the command line. The current version of the software is 0.2.0, and three versions have been released in total, indicating an actively developed project that has progressed through multiple releases. GPX Analyzer is suited to athletes, data enthusiasts, and developers who want a lightweight, dependency-free command-line utility for inspecting and quantifying the contents of GPX activity files, whether for training analysis, data validation, or integration into scripted workflows.
