Drag & drop your Garmin, Wahoo, or Coros .fit file. We parse the raw GPS and timing data instantly.

Get a corrected .fit file ready to upload to Strava. Works with any platform that accepts the FIT format.
Any device that exports the Garmin FIT format — Garmin, Wahoo, Coros, Polar, Suunto, and most modern GPS watches and cycling computers.
The tool lets you specify the exact corrected time. It then proportionally rescales all timestamps within the segment while preserving the relative speed profile — no sudden jumps or unnatural acceleration artifacts.
Input and output files are stored temporarily (7 days) to allow re-downloads, then permanently deleted. We never share or analyse your activity data.
Pay per correction. New accounts get 3 free credits. Credit packs start at $4.99 for 10 corrections — that's $0.50 per file. A monthly subscription option will also be available.
The optional browser extension automatically pulls your Strava segment data into the editor when you're viewing an activity — no manual copy-pasting of segment coordinates. It's not required to use the tool.
KOMGhost produces a valid, standard-compliant .fit file — identical in structure to any file exported from your device. We don't store your identity or link your account to any activity. Your file is processed and deleted within 7 days.
