Every car built after 1996 has an OBD-II port and a story it would like to tell. BlueDriver plugs in and streams it to your phone: engine codes, ABS, SRS and TPMS, live sensor data, repair reports, and a smog-readiness check you can run before driving to the test station.
No subscription — the app and the scan are one purchase. 4.5 stars across more than 63,000 ratings makes it the least risky $140 in a glovebox.
Who should buy: anyone who has ever felt fleeced at a repair counter. Who shouldn't: drivers with a new car under warranty — let the dealer read it for free.
