About this app
Trackr is the all-in-one data logging app built for bracket drag racers.
LOG EVERY RUN
Capture your complete timeslip data — reaction time, 60ft, 330ft, 1/8 and 1/4 mile ET and MPH. Scan timeslips with your camera using AI-powered OCR. Never lose a run again.
PREDICT YOUR DIAL-IN
Get ET predictions based on current density altitude and conditions. See today's best run window with an hourly ET forecast graph. Predictions get more accurate the more you run.
TRACK CONDITIONS AUTOMATICALLY
Auto-fill weather conditions using your GPS location. Multi-tier weather system pulls from the most accurate source available — including your phone's barometer at the track.
MANAGE YOUR CAR SETUP
Track every setup change — jets, timing, tire pressure, shocks, suspension, and more. Named configs let you save and compare different tuning setups. See exactly what you were running on any pass.
SCAN TIMESLIPS
Point your camera at any Portatree timeslip and Trackr fills in your run data automatically. Both sides detected, win/loss auto-assigned.
RACEPAK INTEGRATION
Import Racepak DDF data files directly from your SD card. View engine RPM, clutch data, G-forces, water temp, oil pressure, and more alongside your timeslip data.
MAINTENANCE TRACKING
Never miss a service interval. Track spark plugs, oil changes, clutch inspections, and more by runs, events, or calendar days.
Built by racers, for racers.
