wger is a self-hosted fitness and workout tracker that combines workout planning, nutrition logging, and progress tracking in a single application.
The tool addresses the need for a privacy-respecting, customizable fitness management system. It lets users create workout routines with automatic weight progression, log meals against a food database sourced from Open Food Facts, track body weight and custom measurements, and maintain a photo gallery of fitness progress. The application includes a built-in exercise wiki that users can contribute to, and it exposes a REST API for third-party integrations. Multi-user support enables basic gym management workflows.
wger suits individuals and small gyms seeking self-hosted alternatives to commercial fitness apps. The project is deployable via Docker, making it accessible to users without deep infrastructure expertise. The cross-platform availability through Android, iOS, F-Droid, and Flathub means users can access their data from multiple devices. The tool's strength lies in combining workout, nutrition, and progress tracking in one system rather than requiring separate applications. Community translation via Weblate ensures multilingual support.
The project maintains active continuous integration with automated testing. Code coverage is tracked and publicly reported. The exercise wiki and translation infrastructure indicate ongoing community contribution beyond core development. Development activity spans multiple functional areas including API endpoints, mobile app support, and localization workflows.
