LibreFit - The free and private workout tracker

LibreFit is a free and open-source workout tracker designed with privacy in mind.

Create fully personalized workouts assembled from a rich dataset of hundreds of exercises — each exercise paired with images and step-by-step instructions covering setup and execution.

Schedule single sessions, filter exercises by equipment, muscle group or difficulty with one tap. During workouts, track every set, rep, rest interval, and load in real time.

Thank you for considering improving LibreFit!

You can actively contribute to the project and become a supporter in one of the following ways:

• 💖 Donating
• 🏗️ Contributing to the source code
• 🌐 Translating
• 🏋️ Improving the exercise dataset

Every supporter will be credited in the about page of the app and in credits section, and it will be able to request the supporter version of LibreFit which includes:

• 📝 Custom exercises: The option to create and use custom exercises as they were in the dataset.
• 🎨 Material You: The app's theme will match the colors of system wallpaper.

These features are either cosmetic or obtainable by giving back to the project but by no means this lowers the user experience

💖 Donate

Donations are the main way to:

• Cover costs (e.g. domain, paid plans for emails, etc.).
• Thank and incentivize the creator to invest more time in the project.

To donate, visit the donation page.
