Speed, cadence & power that match your ride

Every gauge reads straight from your GPX or FIT, so the numbers on screen are exactly what your head unit recorded — not estimates. Restyle each one: dial, half-circle, bar, ruler or plain number.

A route map that follows you

Drop in a moving map or a full route trace with a position marker. Make it transparent (no tiles) for a clean look over footage, or use a dark / satellite basemap.

Sync once, export clean

Auto-align the telemetry to your footage from the file timestamp, or nudge it on the timeline. Export an MP4, or a transparent WebM to drop the gauges onto an edit — no watermark.

Multi-clip rides

Action cams split long rides into files. Lay several clips on one timeline and the overlay stays in sync across the whole ride.

FAQ

Is the cycling overlay free?

Yes — completely free, no account, no watermark. Export as many videos as you like.

Which gauges can I show for cycling?

Speed, cadence, power, heart rate, gradient/slope, elevation, VAM, distance, time and a route map — each fully restylable.

Does it read power and cadence?

Yes, if your GPX/FIT contains them (Garmin, Wahoo, most bike computers). Bind any gauge to those channels.

Will it work with my GoPro / Insta360 footage?

Yes. Bring your GPS as GPX/FIT and your camera’s MP4/MOV. A Synced-GPX export also lets you re-align telemetry inside the GoPro/Insta360/DJI apps.

Do I need to install anything?

No — it runs entirely in your browser, on any OS. Your files never leave your device.
