HPDash Racer predicts your ET for bracket racing from your own timeslips, live density altitude, and track wind — and shows its work.

PREDICTION WITH RECEIPTS
Every ET prediction carries a confidence grade and an honest ± window, learned from your own runs — not a one-size correction factor. The app even grades itself against your history: "called within .05 on 14 of 16." When the number moves, it tells you why in plain words: "tailwind gone — your runs had 12 mph tail."

LIVE AIR, MINUTE-SCALE
Airport-grade density altitude refreshed about every 5 minutes, plus live wind from stations minutes from the strip — resolved into head, tail, or crosswind for your lane using the strip's compass heading (pre-loaded for 200+ drag strips). Air density, grains, and SAE power at a glance. Your phone's barometer sharpens the pressure.

TIMESLIP SCANNER + LOGBOOK
Point the camera at a printed time slip and it lands in your drag racing logbook — ET, MPH, 60-foot, splits. Log eighth mile or quarter mile, footbrake or Super Pro. Old runs can backfill the exact air and wind of their moment, down to the minute. Your data exports to CSV any time: it's yours.

WORKS WITH THE DRAGY GPS PERFORMANCE BOX
Stream live runs from a Dragy — 0-60, 1/8 and 1/4 splits with g-force — and calibrate it to match the track clocks. No box? Your phone's GPS can track passes, clearly marked as approximate.

BREAKOUT WATCH
Live sector pace against your dial during the pass: green ON DIAL, red LIFT! when a gate projects a breakout, and BACK ON when you've scrubbed enough to get back in it — with sound and vibration.
