HPDash Racer Dial-In Predictor
Drag racing dial-in & logbook
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
All-new timeslip look. Live wind from stations minutes from the track, priced into your prediction. Breakout warnings mid-pass. No Dragy? Your phone tracks the run.
HPDash Racer is a drag-racing logbook that learns YOUR car and predicts your dial-in from the real air — measured right where you're parked, not guessed from an airport 20 miles away.
LOG IT YOUR WAY
• Type your pass straight off the timeslip — fast between rounds, and it works offline in a dead-zone staging lane.
• Or just snap a photo. Racer reads the numbers off a printed track slip OR a Dragy screenshot and fills the form in for you.
• Batch-import your whole camera roll at once — it sorts detail slips from your history list, pulls the dates, and lets you pick your lane on a two-lane slip.
• Every image is read on your phone. Pictures never leave it.
PREDICTS YOUR DIAL — AND SHOWS ITS WORK
• Every prediction is a fit to your own logged runs — per car, per setup, per distance (1/8 and 1/4 kept separate). Not a generic chart.
• Change the converter, gear, tire, or tune? One tap and the math restarts honestly instead of blending two different cars.
• It never bluffs. Every prediction ships a ± window and an A–D data grade based on how many clean runs you've logged across how much air. If tonight's air is outside anything you've run, it says so.
• Tap SHOW THE MATH to see your runs plotted with the line through them.
MEASURED AIR, NOT GUESSED AIR
• Your phone's barometer reads the true air pressure at your exact spot — the one input weather apps only estimate.
• Live density altitude, air density, grains, and SAE power at a glance.
• AIR AT ROUND TIME projects the air 30–60 minutes ahead so you can write your dial before you run.
• Trackside thermometer beats a distant station — type your own reading and it always wins.
MEASURE RUNS LIVE WITH A DRAGY (OPTIONAL)
• Connect a Dragy GPS box and Racer measures every pass for you — 0-60, rolls (60-130 and more), 60 ft, ETs and trap — then compares each run to its own prediction in real time.
• Works with the DRG69 and the DRG70 "Pro" — auto-detected.
• Each run is saved as a branded timeslip with a speed / elevation / g-force chart and full splits.
YOUR DATA STAYS YOURS
• Everything lives on your phone. No account, no cloud, no ads, no analytics, no data sharing.
• Export your whole logbook to CSV anytime — it's yours.
FREE vs RACER
Logging, photo & batch import, live Dragy measurement, and the full density-altitude readout are free forever. A Racer subscription unlocks the prediction (predicted ET, your dial, the data grade, the ± window, SHOW THE MATH) plus always-fresh, auto-updating air. $34.99/year with a 7-day free trial, or $4.99/month. Your logbook stays readable and exportable whether you subscribe or not.
Built by racers, for racers.

Ratings & Reviews
A big one — new look, new weather intelligence, new ways to run.
ALL-NEW TIMESLIP DESIGN
The whole app now reads like the paper the tower hands you: printed slips, dot-matrix numerals, stamped flags. Distinct day and night looks. Your data, dressed the way racers actually see it.
LIVE WIND, PRICED INTO YOUR PREDICTION
Racer now reads wind from citizen weather stations minutes from the track — updated the moment they report, not once an hour — resolves it against your strip's compass heading (pre-loaded for 200+ tracks), and learns YOUR car's wind sensitivity from your own logbook. Toggle it any time; every reading shows its station, distance, and age.
BREAKOUT WATCH
Live sector-by-sector pace during the pass: green ON DIAL when you're safe, red LIFT! the moment a gate projects a breakout — with optional sound and vibration.
RUN TRACKING WITHOUT A DRAGY
No GPS box? Your phone can now track passes for breakout warnings and approximate splits, clearly marked as phone-measured.
AND MORE
• Add a photo for each car — it follows the car through your runs, predictions, and garage.
• PB flags now name the setup that earned them.
• Sharper live splits that match your printed slips exactly.
