Exercise Diary

Exercise Diary is a lightweight web application for recording and visualizing workouts using a GitHub-style year heatmap. It provides a simple browser UI for entering sessions, viewing yearly activity, and browsing workout entries.

Key Features

• GitHub-style year heatmap visualization for quick activity overview
• Web-based GUI with configurable themes (Bootswatch-based) and light/dark color modes
• Built in Go with a single data directory for storage and settings configurable via config file or environment variables
• Docker image and docker-compose-friendly packaging for easy deployment
• Optional session-cookie authentication with bcrypt-hashed password support and configurable session expiry
• Charts for session details powered by client-side charting libraries; pagination and timezone configuration
• Option to run with local assets to avoid external network dependencies

Use Cases

• Personal workout logging and long-term activity tracking with a compact visual overview
• Quick review of training frequency over weeks, months, and full years for athletes or hobbyists
• Local, private deployment for individuals or small groups who want a simple self-hosted tracker

Limitations and Considerations

• Designed primarily for single-user or small-scale personal use; not intended as a multi-tenant or high-scale service
• Stores data in the local data directory and relies on file-based storage, which may limit advanced querying or scaling
• By default it fetches themes and fonts from the web unless configured to use local assets

Exercise Diary is focused on simple, private workout tracking with an emphasis on visualizing activity over time. It is lightweight to deploy and configurable for local-only environments or small personal servers.
