About this app

Open Road Ace turns your phone or head unit into a pacing computer for open-road races and time-speed-distance (TSD) rallies. Pick a course, set your target speed, and chase 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.

BUILT FOR THE DASH
An 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: a 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 (BBORR North, BBORR South, NORC North, NORC South) plus unlimited custom courses via GPX import.
• RaceBox and ArduSimple BLE GPS support for 10 to 25 Hz precision tracking.
• Full RTK pipeline: NTRIP corrections from any caster, for centimeter-level 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.
