Tools / Compare
Compare FIT, GPX, TCX, JSON, and SML files
Create one saved benchmark event from multiple source files and open benchmark reports on the compare page.
Comparison files are handled after sign-in so saved events, reports, and source metadata stay attached to your account.
Benchmark workflow
Review file recordings without rebuilding a dashboard
Use the compare tool for device reviews, firmware checks, coaching notes, and repeatable FIT, GPX, TCX, JSON, or SML file tests.
Upload two or more FIT, GPX, TCX, JSON, or SML recordings after sign-in and create one saved benchmark event.
Comparison rows can show devices, activity type, distance, ascent, descent, and GNSS, heart-rate, and altitude benchmark error metrics.
Open benchmark reports on this page, add comparison notes, and keep stable device colors for reviewer tables.
