Proven against ten years of BBORR history

Solo. No navigator. Class win.

Open-road racing is a two-person sport: driver + navigator doing pace math at 100 mph. ORA's developer ran BBORR April 2026 alone, with the app as the only navigator. Result: first in 100 mph class, +0.016 sec cumulative across 117.86 miles.

182/182 podium · 152 outright wins

Replayed against every BBORR class published since 2015 — 14 race weekends, 182 class-events. The +0.016 sec result would have podiumed in every single one; won outright in 83% of them.

"On the same race day, a navigator who picked up the app fifteen minutes before the start finished +0.066 sec on his single counted leg — second in 130 mph class. His result alone would have outright-won 99 of the 182 historical class-events."

Hardware: a single $170 consumer Bluetooth GPS module. Three podium-winning teams that day spent under $500 each on receivers, on a course where serious teams routinely run $1,500-$5,000 dedicated rally computers.

Built for TSD rally and regularity, too

TSD rally scoring penalizes one point per second early or late. Regularity events score the same way. ORA's outdoor validation: +0.146 seconds, +10.7 feet across a 1.675-mile target-time run with an ArduSimple RTK kit feeding the iPhone. That's the entire pitch — every $300-1500 rally computer in the discipline exists to do what ORA does at $29.99.

Who it’s for

TSD rally competitors. Regularity rally drivers. Open-road time-trial racers (BBORR, Silver State Classic Challenge, Sandhills Open Road). Anyone whose discipline is scored on hitting a target time to within fractions of a second. Not a track-day app. Not a lap timer. Built specifically for point-to-point precision pacing.

For sanctioned events only

The app does not authorize, sanction, or excuse any violation of traffic laws on public roads. Speed limits posted on public roads remain in force at all times except during properly authorized events. By using the app you assume all risk; see the full Terms of Use & Disclaimer.
