Track-day drivers
Turn a day at the circuit into a clip that actually shows your inputs and your line.
PRODUCTS
Everything RacingLabs builds is aimed at the same thing: helping racing enthusiasts get more out of the data they already record. Right now that means one focused desktop app.
APEXCAST
Apexcast takes the telemetry from a session and the video you filmed of it, and combines them into a finished overlay clip. Import a lap, lay out the widgets you want — digital readouts, round and bar gauges, throttle and brake traces, a GPS track map, a lap timer — and bind each one to a data channel. Sync the overlay to your footage, then export the result. It is a desktop application, built natively for Windows, macOS, and Linux, and it runs offline.
Load a session from RaceChrono, a GPX track log, or a generic CSV, and map the columns to channels.
Add gauge, trace, and track-map widgets to the canvas and bind your data to them.
Line the telemetry up with your video so the numbers match what is happening on screen.
Open two laps side by side on a shared scrubber to see where time is won and lost.
Render the finished clip with hardware-accelerated encoding.
WHO IT'S FOR
Turn a day at the circuit into a clip that actually shows your inputs and your line.
Overlay speed, lap times, and a track map on kart footage from a phone or an action camera.
Compare laps and sessions to find the corners where the time is hiding.
Produce clean, broadcast-style overlays for the videos you publish.
Apexcast reads data from the apps and loggers drivers already use, including RaceChrono. Telemetry from a simulator is one more source it can work with — the app is built for real footage and real data, wherever it comes from.
PLATFORMS & PRICING
Apexcast is free to download and use, with a free tier that covers a full test day. Apexcast Pro removes the limits for a one-time payment of $29 — no subscription, no seats, no per-export fee. Buy it once and keep it, including future updates.
Enough to import a session, build an overlay, and export a clip. A good way to see whether it fits your workflow.
Unlimited sessions, longer renders, full control over output, and lap comparison. Pay once, own it.
Available for Windows, macOS, and Linux.
WHAT'S NEXT
Our focus stays on Apexcast: more of the widgets, formats, and workflow refinements that drivers ask for. We are also working on native versions for Apple platforms so the same tools reach more devices. We would rather ship a small number of things well than promise a long roadmap, so this is deliberately short — but it is real, and it is what we are building next.
