FIT File Parser
Reads a FIT (Flexible and Interoperable Data Transfer) file from a Garmin or ANT+ fitness device and shows the activity summary and per-record GPS/heart-rate samples.

When you'd use this
- Reviewing a workout file recorded by a GPS watch or bike computer
- Checking heart rate and pace data from a fitness activity file
- Inspecting the raw data in a .fit file before uploading it to a training platform
Covers the common fields — activity type, duration, distance, GPS points, heart rate — rather than the full FIT protocol (developer fields are safely skipped, not decoded).
