RoadRush vs OBD2 Scanner

Roadrush turns your iPhone into a precision driving instrument. Built for car enthusiasts, track-day drivers, and anyone who wants to know exactly how they drive, Roadrush combines a real-time GPS speedometer, performance timers, and rich post-drive analytics — all running entirely on-device. REAL-TIME SPEEDOMETER A clean, glanceable speed gauge shows your current speed in km/h or mph, alongside a live metrics panel with average speed, top speed, distance, elevation gained, session duration, and stopped time. Designed to stay readable at a glance, day or night. PERFORMANCE PRESETS Choose how a session is recorded before you pull away: • Standard — open-ended drive, you decide when to stop. • 1/4 Mile — drag-race timer that auto-finishes at exactly 402.336 m. • 0–100 km/h — sprint timer that auto-finishes the instant you hit 100 km/h. Launch detection arms the recorder and starts the clock the moment you take off, so your time isn't padded by reaction delay. DETAILED TRIP HISTORY Every drive is saved to a searchable, sortable archive. Tap any session to see: • The full route on a map, color-coded by speed. • Headline numbers: distance, duration, average and top speed. • Driving dynamics: peak acceleration, peak braking, max G-force, top cornering speed. • Maneuver counts: turns left and right, braking events, lane changes. MANEUVER DETECTION Roadrush analyzes accelerometer and gyroscope data in real time to recognize turns, braking, and lane changes — independent of how your phone is mounted. Peak G-force and cornering speed are captured for every event so you can see how aggressively, and how smoothly, you drove. DRIVER PROFILE Your career dashboard tracks lifetime distance, total time behind the wheel, trip count, fastest 0–100, personal-best top speed, peak G-force, and total maneuvers. Watch your numbers grow drive after drive. CARPLAY READY A full native CarPlay dashboard mirrors your live speed, route, and session metrics on the car's display, with quick access to history and settings. Drive heads-up; review later. BUILT FOR ENTHUSIASTS • Live route map with color-coded speed segments. • Configurable units (km/h or mph) and per-preset launch detection. • Vehicle profile and country selection. • Tuned for accuracy: GPS filtering, sensor fusion, and SI-unit data throughout. PRIVACY FIRST All trips, statistics, and profile data live on your device. No accounts, no servers, no advertising trackers. What you drive is your business. REQUIREMENTS iOS 26 or later.
