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.…
