About this app

Open Road Ace turns your phone into a rally pacing computer. Pick a course, set your target speed, and race a perfect-pace rabbit. A live delta tells you how far ahead or behind class pace you are — at every gate, every corner, every mile.

A NEW LOOK, BUILT FOR THE DASH
Version 1.4 brings a redesigned interface made to be read at speed from a mount or a head unit: a flat dark ground, one big number, and a pace ribbon where a small car (you) chases a rabbit (your target). Green means speed up, red means slow down. Before the start you see your distance to the start line. The screen stays awake and at full brightness while the app is open.

Key features:

• Perfect-pace rabbit — virtual target running your exact class pace, in real time.
• Multi-leg courses with gate-by-gate timing and finish gate detection.
• Built-in courses (NORC North, NORC South) plus unlimited custom courses via GPX import.
• RaceBox and ArduSimple BLE GPS support for 10–25 Hz precision tracking.
• Full RTK pipeline: NTRIP corrections from any caster — sub-centimeter positioning when paired with ArduSimple.
• Optional Kalman filter for smooth position output even on lower-rate GPS.
• Countdown beeps, target-speed dial, automatic foreground service.
• Run history with full GPX export.

One-time purchase. No subscription. No ads. No tracking.

Designed for time-speed-distance (TSD) rally, vintage racing, and any open-road event where holding class pace matters. Built by drivers, for drivers.

What’s new

Two-leg events: pick any course for leg 2 from the between-legs screen. If you back out and start another course within 30 minutes, ORA asks whether to run it as leg 2 of the event. Leaving the leg-2 pre-arm screen keeps your leg-1 carry. The event total no longer counts leg 1 twice. Live display holds at the last speed for 3 seconds when GPS delivery stalls. The car and rabbit marks on the pace ribbon are redrawn so they read at a glance on a head unit.
