CG Lap Bible

CG Lap Bible is a motorsport lap timer and race analysis tool built for karting, cars, bikes, track days and club racing.

Time multiple drivers from one device, follow every lap live and turn each race session into useful insight. CG Lap Bible combines responsive trackside timing with driver profiles, circuit records, weather forecasts, vehicle setup sheets and detailed race history.

BUILT FOR THE START AND FINISH LINE

Capture each driver's start and subsequent laps with simple, dedicated controls. Drivers can start independently, making CG Lap Bible suitable for staggered sessions as well as shared track running.

During a live race you can see:

• Current and completed laps
• Latest and best lap times
• Gaps between drivers
• Faster and slower lap indicators
• Session fastest status
• Live pace and consistency information

Times are recorded internally in milliseconds and displayed clearly to centisecond precision.

UNDERSTAND EVERY DRIVER'S PACE

Open the driver dashboard during or after a session to review best, latest and average laps, consistency, pace trends, personal bests and battle gaps.

CG Lap Bible helps drivers, coaches and pit crews understand what happened across the full session, not just the fastest lap.

BUILD A COMPLETE RACE HISTORY

Save race sessions by circuit, driver and date. Review individual laps, race conditions, personal bests and session summaries whenever you need them.

Compare selected sessions to explore differences in:

• Driver performance
• Lap pace and consistency
• Vehicle setup
• Temperature and weather
• Track conditions

Comparisons are presented as recorded observations, not as claims that one setup change caused a particular result.

TRACKSIDE WEATHER FORECASTS

Check forecast conditions for your current location, including temperature, wind, precipitation and nearby rain intensity. Weather details can be stored with a race so past performances retain their original context.

The rain display is a model forecast and is clearly identified as such inside the app.

SETUP SHEETS FOR KARTS, CARS AND BIKES

Create reusable vehicle setup templates and record the configuration used for each driver and session.

Track tyre pressures, gearing, chassis settings, suspension values and your own custom fields. Review cold-to-hot tyre pressure changes and compare setups alongside lap performance and conditions.

CELEBRATE AND SHARE THE RESULT

When a driver sets a genuine circuit personal best, the Purple Moment gives the achievement the presentation it deserves.

Create polished race cards for sharing results, rankings and best laps. Setup Passports also make it possible to transfer compatible setup information between devices using an offline QR code.

PRIVATE BY DESIGN

CG Lap Bible is a local-only app. No account, login or cloud sync is required.

Race history, driver profiles, setup sheets and notes are stored on your device. Built-in backup and restore tools help you protect and transfer your records.

Whether you are timing from the pit wall, coaching a kart driver, comparing track-day sessions or building a racing setup notebook, CG Lap Bible keeps every lap, setup and condition together in one focused motorsport tool.
