Overlay speed, heart rate, altitude, grade, and GPS trail position onto mountain biking footage.
Pair GoPro or chest-mount footage with FIT data from a Garmin watch or bike computer. MetricsOverlay syncs them by timestamp.
Speed overlay shows GPS-derived km/h or mph. Useful for showing how fast technical sections actually are. Heart rate shows the effort behind the footage.
GPS map renders the trail with your live position. Overview shows the full trail. Follow mode tracks you through switchbacks.
