Then the report
A code is a number. This is an answer.
The AI doesn’t recite the code definition. It reads your vehicle, the live data around the fault, and known failure patterns for that engine. On a P0301 it doesn’t just say “cylinder 1 misfire” — it tells you the misfire is dumping raw fuel into your exhaust, and that leaving it turns a modest repair into an expensive one.

How it works
Three steps, no technical expertise.
- 01
Plug in
Connect an ELM327 Bluetooth adapter to your car's OBD-II port, usually just under the dashboard on the driver's side.
- 02
Scan
Open the app and tap scan. It pairs with the adapter, reads every stored trouble code, and starts streaming live engine data.
- 03
Get the report
A plain English explanation of what is wrong, ranked likely causes, whether it is safe to drive, and what the repair should cost.
Hardware
Adapters we’ve actually tested.
Not all OBD-II adapters are created equal. We look for genuine ELM327 chips and Bluetooth Low Energy (BLE) support — the combination that delivers fast, reliable connections with minimal battery drain.
Veepeak OBDCheck BLE+
Reliable Bluetooth Low Energy adapter with broad vehicle compatibility. Genuine ELM327 chip with fast, stable connections.
Vgate iCar Pro BLE
Compact, low-power adapter with excellent connection stability. Supports all standard OBD-II protocols out of the box.
Also compatible
Veepeak OBDCheck BLE
Budget-friendly BLE adapter from Veepeak. Solid basic option that handles standard diagnostics well.
Vgate vLinker MC+
Feature-rich adapter with broad protocol support. Good choice for users who want extra flexibility.
Generic OBD-II BLE Adapter
Basic unbranded BLE adapter. Works for standard scans, though connection stability can vary between units.
Any ELM327-compatible BLE adapter should work, but these are the ones we've verified firsthand for the best experience.

Questions
Before you ask.
OBD-II (On-Board Diagnostics II) is a standardized system in all cars sold in the US since 1996. An ELM327 adapter plugs into your car's OBD-II port (usually under the dashboard) and communicates wirelessly with your phone via Bluetooth.
