wger

wger is a self-hosted fitness and health management system designed to track workout routines, nutrition, and body measurements. It operates as a web application that users can deploy on their own servers to maintain full control over their personal health data, ensuring that sensitive biometric and dietary information remains private and under the user's direct administration.

The software allows users to plan exercises and monitor physical progress over time. It is deployed primarily via Docker for simplified installation and maintenance, though it is also available as a set of cross-platform applications for Android, iOS, F-Droid, and Flathub. These mobile clients facilitate real-time logging during workouts and allow users to access their health data while away from their home server.

Key features

• Custom workout routines with automatic weight progression rules
• Diet plan tracking and body measurement logging
• Calorie logging using a food database from Open Food Facts
• Progress gallery for uploading and tracking fitness photos
• Built-in exercise wiki for accessing and contributing exercise data
• REST API for third-party integrations and automations
• Multi-user support with basic gym management features
• Community-driven multilingual support via Weblate

Built with Python and the Django framework, wger provides a structured environment for both individual athletes and small gym managers. The system relies on a combination of AGPL-3.0 licensed code and Creative Commons licensed data for its exercise and ingredient libraries. Its architecture supports external integrations through a dedicated REST API, allowing users to automate data entry or connect the system to other health tools and custom scripts. The inclusion of a community-contributed exercise wiki ensures that the database of movements remains current and diverse.

This application serves as a comprehensive tool for individuals who prefer to self-host their fitness and nutrition data rather than relying on cloud-based services. It is intended for users who require a flexible, open-source system to manage long-term health goals and physical training cycles.
