What is FitFileExplorer?
FitFileExplorer is a macOS application published by Ro-z for opening and exploring FIT activity files. The official product page describes it as an open source utility focused on showing the information stored in a FIT file directly, instead of reducing it to a simplified workout summary. It is used by developers, data-focused athletes, and advanced users who want to inspect records, laps, fields, and other structured data inside Garmin-style activity files. The app can graph values from selected data columns, and it can display a map when the file contains GPS coordinates. The official product information also notes CSV export support and a file download function for opening FIT data from a Garmin account. Users may encounter it when analyzing workout files from devices and services that store activity data in the FIT format.

Safety overview
Status: Mostly safe
FitFileExplorer is a legitimate user-installed app for reading FIT workout files. It is not known as malware from the verified product information, but FIT files can contain sensitive health, location, and activity data, so users should treat imported files and any exported CSV data as personal data.
Recommendation: Keep it if you review or analyze FIT activity files on your Mac. Remove it if you do not use FIT data inspection, CSV export, or file-based workout analysis features.
