DriveInsight: OBD2 Car Doctor

DriveInsight turns an inexpensive ELM327 adapter into a diagnostic tool that explains what your car is doing, in words instead of codes. SEE THE FAULT, NOT JUST THE CODE Stored fault codes come back grouped by the system they belong to — transmission, engine, ignition, fuel and air, emissions — each with a plain description rather than a five-character code you have to look up. Clear them once you have fixed the cause: the app re-scans afterwards, so you find out whether the fault actually went away or came straight back. WATCH THE GEARBOX WORK Generic OBD-II says almost nothing about the transmission. DriveInsight works it out from engine speed and road speed alone: how many gears your car has, which one it is in right now, and how far the engine is turning above the gearing. That last figure is torque converter slip, and it climbs long before a gearbox fails. The app learns your car as you drive and remembers what it learned between trips. LIVE READINGS THAT MEAN SOMETHING Engine speed, road speed, coolant and oil temperature, intake air, fuel trims, oxygen sensors, manifold pressure and more — each shown against the range it should sit in, so an unusual number stands out without you having to know the specification for your engine. ASK ABOUT WHAT YOU ARE SEEING Premium adds an AI reading of your live data and stored faults: what is likely wrong, how urgent it is, and what the repair usually costs. You can ask follow-up questions about your own car's numbers. Works with any ELM327 Bluetooth OBD-II adapter. Reading codes and watching live data needs no account. Premium is an auto-renewing subscription. Payment is charged to your Apple ID account at confirmation of purchase. It renews automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel in your Apple ID settings.
