The Multi-Device Difference

Why settle for crowding around a single smartphone suspended over the track? Gepetto Lap Counter distributes race roles across your local network so everyone gets the perfect view.

Distributed Ecosystem Roles

Overhead Camera Device

Use a smartphone suspended over your start/finish line, or connect a USB camera directly to your computer. It acts purely as the high-speed optical lap detection sensor.

Race Steward Panel

Hold a second phone or tablet in hand to marshal heats, add/remove drivers, start races, and enforce penalties.

Personal Driver Displays

Place tablets or smartphones at each driver station for dedicated real-time lap times, gaps to the leader, and personal best laps.

Stadium TV Billboard

Connect a Smart TV, desktop PC, or tablet to display live leaderboards and sector times for spectators.

Built for Precision & Convenience

Advanced computer vision optics combined with intuitive race management tools.

High-Speed Timing Precision

Timing granularity scales with your camera's frame rate—ranging from a minimum of 1/30th of a second on standard phones, 1/60th of a second on modern smartphones, up to 1/150th of a second with advanced USB cameras attached to your computer.

Optical Baseline Vision

Advanced image differencing compares real-time camera frames against a static track baseline. Eliminates false lap triggers from passing shadows—making it a snap to set up without requiring proprietary, hard-to-setup hardware.

Local Network Sync

Instant peer-to-peer communication using WebSockets and Google Quick Share protocols. Zero latency standings across all connected devices.

Voice Lap Announcements

Hear lap times and lead changes announced aloud in real time so drivers can stay focused on the track ahead.

Championship & Heats

Full race manager features: rotation of drivers across lanes, heat scoring, overall leaderboard tracking, and session histories.

Available on All Your Devices

Android App

Full camera tracking, race steward controls, and billboard displays on any Android phone, tablet, or TV.

Desktop (macOS & Windows)

Native high-performance desktop app. Connect a USB camera directly to your computer or link wirelessly to a camera phone over your local network.
