Apexcast

Turn your track footage into broadcast-grade onboard video. Drag-bind your telemetry to 45+ widgets, scrub by lap, and render in minutes.

Apexcast turns your on-track footage and telemetry into broadcast-grade onboard video — built natively for Apple Silicon.

Import a lap video and a telemetry log (RaceChrono CSV and more), sync them once, and compose overlays from a library of 45+ widgets: speed and RPM gauges, steering wheel, G-force, GPS track maps, lap timers, sector deltas, stats rows, and more — each with multiple themes and full color control, including an in-app eyedropper.

WHY RACERS USE IT • Native performance: preview scrubs at full frame rate; renders run on the GPU via Metal and VideoToolbox. • Compare mode: play two laps in lockstep with a shared transport and a live time-delta lane — see exactly where the time comes from. • Lap-aware timeline: scrub by lap, align the sync point manually when GPS drifts, trim non-destructively. • Project templates: save a widget layout once, apply it to every session. • Offline-first: your footage, telemetry, and projects never leave your Mac. No account required.

FREE AND PRO Apexcast Free includes up to 3 sessions, 3 widgets per canvas, and renders up to 3 minutes at 1080p60. Apexcast Pro — a one-time in-app purchase — unlocks unlimited sessions, unlimited widgets, unlimited render length, and full output control including 4K.

Made for track-day drivers, karters, club racers, and anyone who wants their onboard videos to tell the whole story.
