# Drag Race Logbook Pro

> Drag Race Logbook Pro is a drag-racing logbook and ET prediction app for bracket, sportsman, class, and junior dragster racers.

Drag Race Logbook Pro helps racers turn paper time slips and run history into practical race-day decisions. The product combines photo-based time-slip and logbook capture, structured run records, weather and density-altitude context, reaction-time practice, and ET prediction based on a user's own car history.

## Core answers

- Drag Race Logbook Pro tracks cars, tracks, time slips, weather, reaction time, ET, MPH, dial-in, and maintenance notes.
- The time-slip scanner extracts common drag-racing fields such as RT, 60-foot, 330-foot, 660-foot, ET, and MPH; users review and edit extracted values.
- The ET predictor uses logged runs and density-altitude conditions to estimate expected performance for a specific car.
- The Practice Tree simulates Pro Tree, Full Tree, and Junior Dragster timing for reaction-time training.
- The density-altitude calculator uses temperature, humidity, and pressure to estimate the air density a car will experience.
- Users can export their run history and retain ownership of their racing data.
