Supporting Open Source Fitness Tech 🚴‍♂️💪

Hey! I'm building Kaiord – an open-source toolkit that makes workout data actually usable. If you've ever struggled with converting between FIT, TCX, or PWX files, or wished there was a clean, JSON-based format for structured workouts, this project is for you.

What I'm working on:

🔄 Round-trip safe conversions between fitness file formats

📋 A human-readable JSON format (KRD) for workout data

🏗️ Clean architecture with TypeScript, full test coverage

🛠️ CLI tools and libraries for developers

Every coffee helps me dedicate more time to:

Adding support for more formats and devices

Improving documentation and examples

Building features the fitness dev community actually needs

Maintaining quality code that others can learn from

If Kaiord has saved you time or helped your project, consider buying me a coffee! Your support keeps this project alive and growing. ☕
