Exercise Diary

Exercise Diary

Web-based workout diary that visualizes activity as a GitHub-style year heatmap. Built in Go, configurable via file or env, Docker-ready with optional authentication and themes.

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.

Wingfit is a minimalist, privacy-first web application for planning workouts, logging sets/reps/weights and tracking personal records (PRs). It focuses on clear progress visualization and can ingest smartwatch data to augment logging.

Key Features

  • Structured workout planning and session templates for sets, reps and weights.
  • Persistent tracking of personal records and progress visualizations.
  • Ability to leverage/import smartwatch data to enrich workout logs.
  • Privacy-first design with no telemetry or tracking; data is stored on the host.
  • Simple deployment using Docker and a provided docker-compose configuration (volume-backed storage).
  • Optional configuration for external authentication (OIDC) and environment-based settings.

Use Cases

  • Individuals who want a lightweight, self-hosted tool to plan and log strength training sessions.
  • Athletes who want a private, local record of PRs and progress visualizations without cloud telemetry.
  • Users who collect smartwatch activity data and want to import it into a focused workout/PR tracker.

Limitations and Considerations

  • Wingfit is intentionally minimal: it focuses on workouts and PR tracking and does not provide built-in nutrition, social features, or a full gym management suite.
  • The primary storage option is SQLite by default; this is convenient for single-instance/self-hosted use but may not suit large multi-user deployments without migration to a different database.
  • There is no first-class mobile/watch app bundled; smartwatch data is leveraged/imported rather than relying on a native companion app.

Wingfit is distributed under a license that permits modification and sharing for non-commercial use. The project is open-source, actively maintained on GitHub, and provides a live demo and Docker images for quick evaluation and deployment.

Workout Challenge

Workout Challenge

Host group fitness competitions with manual or Strava-imported workouts, customizable goals, leaderboards, streaks and scheduled email reports.

Workout Challenge is a web application for running private group fitness competitions. Participants add workouts manually or link their Strava account for automatic imports, then compete using customizable metrics, periods and point rules while tracking leaderboards and personal progress.

Key Features

  • Create and join competitions via invitation links with configurable goals (time, distance, calories, count)
  • Multiple goal periods: per day, week, month or whole competition; configurable min/max per workout/day/week
  • Manual workout entry and automatic Strava import with scheduled daily syncs handled by background workers
  • Personal dashboard with stats, streaks and progress; competition dashboards with friends' activities and leaderboards
  • Weekly automated emails (leaderboard and optional personal progress reports)
  • Responsive UI with light/dark modes; Docker support and a production-ready docker-compose setup

Use Cases

  • Run a workplace or friend group steps/minutes/distance challenge with per-user tracking and leaderboards
  • Aggregate workouts from Strava for teams and present weekly leaderboard reports via email
  • Host multi-goal competitions (e.g., distance + minutes) with caps to encourage consistent, healthy activity

Limitations and Considerations

  • Automatic imports rely on Strava OAuth and are subject to Strava API rate limits; administrators must register API credentials
  • Background processing requires a task broker and worker setup (Celery) and optional Redis for caching in production
  • Email notifications require a configured SMTP provider to send scheduled reports
  • No official native mobile apps; site is responsive but mobile experience depends on browser

Workout Challenge is focused on privacy-respecting, configurable group competitions and is packaged for containerized deployment. It is suitable for small teams or communities wanting a lightweight, self-hosted fitness challenge platform.
