HPDash Racer Dial-In Predictor

Drag racing dial-in & logbook

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

Log your passes by hand or just snap a photo, and Racer learns your car — then predicts your dial from the real air measured right where you're parked. No guessing. 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. ## What's New (v1.0) (4000) First release. Log by hand or by photo/batch scan, predict your dial from measured air, and — with a Dragy — measure your runs live.

  • This app hasn’t received enough ratings or reviews to display an overview.

Dragy runs just got a lot sharper. • More accurate ETs — runs are now calibrated against real track timeslips, so your numbers line up with the clock. • Cleaner timeslips — the chart shows just the pass instead of the shutdown and roll-back, with smoothed speed, g-force, and elevation. • G-force at every gate — see the g you pulled at 60 ft, 330, 1/8, 1000 ft, and 1/4, with peak g marked on the chart. • Density Altitude on every run — know the exact air each pass was made in. • Smarter validation — flat strips and post-run signal drops no longer get falsely flagged invalid. • Runs end when the pass ends — no more long recordings that dragged in the return road. Your existing runs are re-scored automatically the first time you open this update — nothing to redo. Plus full iPad support with a two-pane layout.
