Best Free & Open Source Alternatives to MyFitnessPal

wger (pronounced "vega") is a free, open-source workout and fitness manager that you can self-host or use via official mobile apps. Built with Python and Django, it provides a complete solution for tracking workouts, nutrition, body measurements, and progress photos without relying on proprietary subscription services.

The platform includes a built-in exercise wiki with a community-contributed database, custom workout routines with automatic weight progression rules, and nutrition management powered by Open Food Facts. It supports multiple users with basic gym management features and offers a REST API for third-party integrations.

wger is available as a web application that deploys easily with Docker, and through cross-platform mobile apps on Android, iOS, F-Droid, and Flathub. The project is actively translated by the community via Weblate and released under the AGPL-3.0 license.

SparkyFitness is a self-hosted fitness and health tracking platform you run on your own server. A web app, native iOS and Android apps, and Apple Watch and Wear OS companions all share one backend, so nutrition, training, hydration, sleep, fasting, mood, cycle and body measurements live in a single database you control. SparkyFitness is source-available rather than open source: the license permits non-commercial use, modification and redistribution, and commercial use requires the author's permission.

Key Features

• Nutrition tracking: log meals and custom foods, pull items from Open Food Facts, USDA, Fatsecret, Nutritionix, Mealie, Tandoor, Norish and national food databases, and review trends in interactive charts.
• Training: exercise library backed by Free Exercise DB and Wger, strength sets, interval and WOD workouts, guided workouts, GPS activity recording, training programs, and adaptive weight suggestions.
• Daily logging: water intake with custom containers, sleep, fasting, mood and mindfulness, medications and supplements, symptom tracking, progress photos and body measurements.
• Cycle Hub: cycle tracking with dedicated trying-to-conceive and pregnancy modes.
• Family and friends sharing: multiple profiles with granular per-user permissions.
• Integrations: Apple Health, Google Health Connect, Fitbit, Garmin Connect, Withings, Polar Flow, Oura, COROS, Hevy, Strava and Intervals.ICU.
• SparkyAI and MCP: an optional beta assistant that logs food, exercise and body stats from chat or a meal photo, plus an MCP server so external AI assistants can read and write your data.

Self-hosting

Docker Compose brings up the server in a few commands, and a browser-based .env generator produces the required database password, encryption key and auth secret. OIDC single sign-on, TOTP, passkeys and MFA are built in. If you would rather not run a server, third-party hosts such as PikaPods and Zenith offer one-click deployments.

How it compares

SparkyFitness replaces several paid subscriptions at once: MyFitnessPal or Cronometer for food logging, Hevy for strength training, Flo for cycle tracking, and fasting apps such as Zero, all without per-person fees or ads. Reporting spans the full history rather than gating long date ranges behind a paid tier.

NutriTrace is a self-hosted personal nutrition tracker designed for privacy and full data ownership. It runs as a single Docker container on your own hardware, offering both a Progressive Web App (PWA) for browsers and a native Android app. No accounts on external services are required, and no data leaves your network unless you explicitly opt into third-party integrations.

The app features a daily food diary with configurable meals, quick-add foods and recipes with portion scaling, and a nutrition bar with macro summaries. You can track body stats, water intake, and even intermittent fasting with customizable goal presets. A built-in AI assistant (Trace) can answer questions about your nutrition data.

NutriTrace supports importing past data from MyFitnessPal, Lose It!, Cronometer, or generic spreadsheets, making migration straightforward. The personal food database supports photos, barcodes, and custom labels, with barcode scanning via Open Food Facts.

Multi-user support is optional — it runs perfectly as a single-user app without any login. For multi-user setups, admins can invite users via email or shareable links, enforce strong password policies, and enable biometric sign-in on Android.

Stronk is a free, open-source weightlifting tracker built as an installable web app. It keeps the focus on the essentials of lifting: logging workouts as you train, recording sets, reps and weights for each exercise, and reviewing how your performance changes over weeks and months. Because it is a progressive web app, you can install it straight from the browser onto your phone or desktop, and it behaves like a native app once on your home screen.

Privacy is built into how Stronk works. There are no accounts to create, no subscriptions to pay, and no third-party tracking — every workout you log is stored locally on your own device. The project is committed to staying free, and cloud backup for cross-device sync is under development for users who want an extra layer of safety for their training history.

Stronk is a good fit for lifters and home-gym users who find commercial training apps bloated or paywalled. If you want a straightforward, private way to track your lifting — without the ads, upsells, or data harvesting of apps like Hevy, Strong, or MyFitnessPal — Stronk is worth a look. The source code is available on GitHub under the GPL-2.0 license, and the project welcomes feature requests and pull requests.

HealthCoach is a personal health tracker built with Kotlin Multiplatform and Compose Multiplatform. It runs as a desktop app on Linux, Windows, and macOS and as a native Android app, and stores everything in an embedded SQLite database on the device. There is no account system and no telemetry: the app does not contact any server unless you configure sync yourself.

The app covers three tracking areas in one place. A food journal splits meals into breakfast, lunch, dinner, and snacks, keeps a reusable food library with serving sizes and calorie densities, recalculates calories as you change portions, and shows daily intake against a maintenance baseline and a goal. Goals come from a Mifflin-St Jeor BMR and TDEE estimate and can be set as a weekly rate, a target weight by date, or a manual calorie adjustment. Weight entries are grouped by month with net-change summaries and color-coded deltas, and blood pressure logs capture systolic, diastolic, and optional pulse readings with automatic American Heart Association classification from normal through hypertensive crisis. A compound chart layers weight, blood pressure, pulse, and calorie intake on independent axes.

Sync is opt-in and peer-free. You can point HealthCoach at a local folder or a mounted cloud drive, authorize its own Google Drive appDataFolder with PKCE OAuth, or pair a desktop and an Android device over the local network with mDNS discovery and PIN authentication. A three-way BASE/LOCAL/REMOTE merge with last-write-wins on update timestamps and a schema-version check keeps devices consistent without a central server.

HealthCoach replaces the paid subscription tiers of calorie and weight-loss apps for the tracking part: the daily food log, calorie targets, weight history, and progress projections that MyFitnessPal, Cronometer, Lose It!, and Noom charge for. It also stands in for dedicated blood pressure logbooks. It is not a medical device, and the AHA categories and metabolic numbers are reference calculations rather than advice.
