Swim Data Analyser

Browser-based tool to analyze swim workout data from Garmin FIT files, fully client-side.

Webfree

Swim Data Analyser is a browser-based tool for manipulating and analyzing swim workout data from Garmin FIT files. All parsing happens client-side, so files never leave the user's device, and the tool can also be self-hosted as a static site. It's aimed at swimmers who use Garmin devices and want to review their swim data without uploading it to a cloud service.
