One OBDII

A full OBD-II scan tool, live gauge clusters, racing camera, and a 0–60 timer — from one Bluetooth adapter and your iPhone. EVERY DIAGNOSTIC FUNCTION IS FREE • Read and erase trouble codes, with a clear warning before any erase • I/M readiness: see whether your car is ready for a smog check • Live data from every sensor your car reports • Freeze frame and vehicle information, including the VIN • O2 sensors and the O2 sensor test • On-board monitoring results, misfire counters and EVAP • An offline trouble-code library — look up any code, no car needed • Scan history and PDF reports you can share When the car doesn't answer, the app says so plainly — "ECU is not responding" — instead of guessing. TIMER — FREE 0–60 mph, 0–100 km/h, 40–100 and more, timed from your car's own speed sensor. With no adapter it falls back to the phone's GPS and tells you, because a GPS time is a ballpark. GAUGE CLUSTER The free Classic cluster shows two dials and four bars, and each can show any reading your car reports. The one-off unlock adds: • Your own layouts on the grid — move and resize anything • Premade cluster styles • Shift bars, a G-meter and a gear indicator • Every gauge face, colour and theme • R-Cam: record video with your car's live data drawn into it, saved to Photos Buy it once and it's yours. No subscription. WHAT YOU NEED • An ELM327 OBD-II adapter that uses Bluetooth LE (4.0 or later). iPhones cannot connect to "Classic" Bluetooth OBD-II adapters, and Wi-Fi adapters are not supported. • A car with OBD-II — most cars and light trucks sold in the US from 1996 on. No adapter yet? The demo drive replays a recorded drive through the whole app. PRIVATE BY DESIGN No account, no ads, no tracking. Your scans stay on your phone.
