Garmin FIT SDK

The Flexible and Interoperable Data Transfer (FIT) protocol is Garmin's compact binary file format for sport, fitness, and health data — activities, courses, workouts, monitoring files, settings, and more. The FIT SDK ships encoders and decoders in eight languages (C, C++, C#, Java, JavaScript, Objective-C, Python, Swift), the FitCSVTool for binary-to-text inspection, FitGen.exe for profile customization, and the canonical Profile.xlsx defining every FIT message and field. FIT is the de-facto interchange format across Strava, TrainingPeaks, Komoot, Wahoo, Polar, Suunto, Apple Health, Google Fit, and the entire endurance-sport tooling ecosystem.
