1Drag Live

1Drag turns your phone into a drag strip timing system. Stage, launch, and get a full timeslip: 60 ft, 330, 1/8, 1000, 1/4, 1/2 mile and the standing mile with trap speeds, plus 0–60, 0–100, 0–130, 60–130, 100–150 and metric brackets, peak g, slope and a speed trace. Times use a one-foot rollout like a drag strip, and every run is graded on GPS quality and road slope so you know how much to trust it. TIMED FROM YOUR CAR'S OWN SPEED Plug in an OBD-II adapter and 1Drag times the run from the car's own speed reading, checked against GPS: no phone-GPS lag off the line, so 60 ft and trap speed come out right. LEADERBOARDS Post a run to the 1Drag leaderboard for 0–60, 1/4 mile, 60–130 and more. Runs timed from the car's speed or a 10 Hz GPS on a flat road earn a Verified badge. Filter by make, this week, or all time. A FULL CHRISTMAS TREE Run a Sportsman or Pro tree on your own phone, full screen so you can see it from the driver's seat, with a distinct sound for each amber and the green. Reaction time is measured from the green, or let Launch Detect start the clock the instant the car moves. HORSEPOWER YOU CAN EXPLAIN Estimates from trap speed, from ET, and from road-load physics on every run. A coast-down mode measures your car's real aero drag and rolling resistance so the numbers use your car, not a guess. BUILT FOR TRUCKS TOO Hill Pull and Downhill Brake Test score a tow the way the big gauntlet tests do: sustained power on the grade with trailer weight, time held at target speed, brake applications, and overshoot. LAPS AT THE TRACK Circle track or road course. Mark the start/finish line before the session, or save the track once and 1Drag finds it every time you come back. Every lap and sector is timed live, with a running delta to your best lap and voice callouts ("Lap 4. 24.10. Best lap.") so you never read the screen at speed. Afterwards: a map of the track drawn from your own line, sector times with your best in purple, a theoretical best lap, and a corner-by-corner verdict: wide, pinched, or slow. VIDEO WITH YOUR NUMBERS Import the clip from any camera (action cam or phone), line it up on the launch, and watch speed, the clock and your splits over the picture. On Android, export it with the overlay burned in. RACE SOMEONE, LIVE 1Drag Live pairs two phones on one race code. See the other lane's speed and splits as they happen, launch on the same green from a synced tree, and get both timeslips at the stripe. Hosts can run an event with a TV board showing every pass and the leaderboard. ENGINE GAUGES AND SCANNER With an OBD-II adapter: a custom gauge dash with a floating gauge over other apps, trouble codes in plain English, readiness monitors, the VIN decoded, and every live channel the car reports. REPORTS AND SHARING Shareable timeslip images, PDF reports, run compare, CSV, VBO and GPX export, track timeslip entry with weather and density altitude, and full backup and restore of your runs. MORE ACCURACY WHEN YOU WANT IT Pair a RaceBox Mini, Mini S, or Micro over Bluetooth for 25 Hz timing with Doppler speed. By 0101 Inc. GPS timing is not a certified timing system; horsepower figures are estimates. Race on a track or a closed course.

Tablets and foldables: 1Drag now fills a tablet or an unfolded Galaxy Z Fold, with side-by-side panes and landscape; phones stay in portrait. Steadier starts: a run only begins when the phone's motion sensors feel the car launch, so GPS drift on a weak fix can't start one while you sit still. Laps: parking near the start/finish no longer counts as a lap. Plus Verified leaderboards, OBD-II speed timing, video overlays, sectors and a live delta.
