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.

If your slip says 11.174, that's what the app logs and what your predictions are built from. CALIBRATION RE-FIT TO THE TRACK ET calibration was re-fitted against real track clocks across multiple facilities. If you were running a per-car SLIP CAL trim to make your Dragy match the timing system, clear it after updating — the correction is now in the baseline. DRAGY • Battery level right on the panel, with a gauge that turns amber then red as it drops — so a dying box is caught before the pass, not during it. • 0–60 timing fixed: creeping through the burnout box no longer starts the clock, which was turning a 3-second launch into an 8-second reading. • 25 Hz option for DRG70 and DRG70 Pro — 2.5× the samples through every gate, for sharper splits. Off by default; turn it on in the Dragy panel. • Restore your saved Dragy runs — traces, splits and personal bests — from a backup after a reinstall or a new phone. PERSONAL BESTS Your quickest clean pass per car and setup now wears a PB flag in RUNS, scoped exactly the way your predictions are: change the combination and the PB starts fresh with it. EVENTS Search the full track database by name, city or state — useful for planning a tow, and it works with location off. Nearby events and closest-first tracks are unchanged. PREDICTIONS The prediction panel no longer goes blank for subscribers who haven't added a car yet — it now points you to the Garage instead of disappearing. LOOK AND FEEL Buttons and chips rebuilt with the same machined edge and gradient as the rest of the app, and button borders now sit flush instead of a hair proud. Long labels no longer break mid-word on narrow screens. The theme toggle says LIGHT or DARK — whichever mode you're in. Plus a link to the Racer guide in the About section. ### 0.1.4 — 2026-08-13 Racer subscribers: the prediction panel now shows up the moment you're active — on a fresh install it walks you straight to adding your car, instead of staying hidden until your first runs were logged. RESTORE DRAGY: moving phones or reinstalling? Your saved Dragy runs — traces, splits, g-data, personal bests — now restore from a backup file. RUNS tab, RESTORE DRAGY, pick your dragy-results.json. ### 0.1.2 — 2026-08-12 EVENTS — a whole new tab. Drag racing events near you, closest first, pulled automatically from track schedules across the country. Plus the 250+ strips nearest you with each track's own schedule page one tap away. SCAN ANY TIMESLIP. The slip scanner now reads CompuLink tickets — the timing system at NHRA-standard tracks — alongside Accutime. Between them, that's the printout at most strips in the country. And SCAN SLIP now opens the camera directly: shoot the slip in your hand, review, save. (Gallery import is still right next to it.) PREDICTIONS FOR YOUR SPEED RUNS. Every Dragy speed gate (0–60, 40–100, 60–130…) now shows PRED — your car's expected time in tonight's air, fitted from its own best pulls. Beat the line and it glows green. DRAGY FIXES FROM THE TRACK. • Recordings now end right at the top end at eighth-mile tracks too — no more 40-second runs to the turnout. • Slip calibration re-fitted against real track clocks at two facilities, plus a per-car SLIP CAL trim in the Garage if your slips ever disagree. • Dragy Pro GPS readiness no longer reads "weak" on a clean sky. MORE. • DATA GOOD THRU gains "TO THE 1000'" — hurt parts after the 1000-foot? The rest of the pass still counts. • New FEEDBACK panel in the Garage — bug or idea, straight to the developer. ### 0.1.1 — 2026-08-08 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. ### 1.0 — 2026-08-07 No release notes. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
