Drag Race Logbook: ET Dial-In

Snap the time slip. The pass is logged. Your next dial-in is waiting.

Drag Race Logbook is the logbook and ET predictor for bracket racers. It reads your time slip, files the pass against the right car with the weather from the moment it was run, and predicts your next ET from your own passes and the air at the track.

SCAN, DON'T TYPE
• Photograph a time slip and it reads every number: reaction time, 60 ft, 330, eighth mile, 1000 ft, ET and MPH
• Picks your lane by your car number, not whichever column is on the left
• Several slips in one photo become several passes
• Quarter-mile and eighth-mile slips both work
• Import your old handwritten log sheets too

PREDICT YOUR ET
• Live density altitude, temperature, humidity, pressure, dew point, grains of water and wind at your track
• Predicted ET built from your own passes and corrected for density altitude, track elevation and wind
• A report card grades the predictor on your passes, so you know how far to trust it
• Passes the predictor leaves out are marked with the reason

WEATHER YOU CAN TRUST
• Every pass shows where its weather came from
• Import a Kestrel, Computech or Altronics weather file
• Old passes get the air from the day they ran, not today's

A LOGBOOK THAT WORKS LIKE YOU DO
• Timeslip or Log sheet layout
• Filter by car, see passes by day and spot your quickest run at each distance
• Group passes by event with run type, class and round
• Log your opponent's name and car number and see how you did last time
• Breakouts and red lights flagged straight from the slip
• Search everything, compare runs side by side, export to CSV, Excel or JSON. It's your data

YOUR DIGITAL GARAGE
• Every car with its number, classes and setup notes
• Custom setup fields per car, including throttle stop
• Maintenance for any part by run count or days, so nothing gets missed
• Share a car with your crew or tuner so everyone works from the same logbook

SHARPEN YOUR LIGHT
• Practice tree with Pro (.400) and Sportsman (.500) trees
• See your reaction times across the season

SEE THE PATTERN
• ET against density altitude with the trend line drawn
• Spread, average reaction, red lights and season best

ON YOUR WRIST
• Wear OS companion: each car's predicted ET at a glance, and the bezel sets your dial-in and saves it to the phone
• Lanes mode shows the dial in big type for the staging lanes
• Add the Up Next tile or the dial complication to keep the next car's number one swipe away
• Works with the phone app; the watch shows what the phone sends

Built for bracket racers and just as useful in heads-up classes. Door car, dragster or junior dragster, the numbers are the numbers.

Your logbook syncs with the web app at dragracelogbook.com, so what you log in the staging lanes is on your laptop when you get home. Available in English, Spanish, Portuguese and French.
