W·01SPD
Speed trace & speedometer
Live speed straight from the GoPro GPS, as a dial readout or a trace across the lap.
GoPro telemetry → racing HUD
Your onboard, with TV‑broadcast telemetry.
HUDmentar reads the GPS, speed and g-force your GoPro already records inside the video, and burns a racing HUD over it. No extra sensor. Export the finished clip, ready to post.

Real footage. Real HUD.
A GoPro clip from a kart race with the HUDmentar overlay burned in — the same video you export.

Time gained or lost against your best lap, at every instant.
W·03MAP
