COMPATIBILITY
Works with most gasoline cars and light trucks sold in the US since 1996, EU petrol cars since 2001, and diesel since 2004 (OBD2 / EOBD / JOBD). Supports all standard OBD2 protocols including CAN.

REQUIRED ADAPTER
You need an ELM327-compatible OBD2 adapter:
- Bluetooth LE (4.0+) or Wi-Fi adapters work with iPhone
- Classic Bluetooth adapters do NOT work with iOS (Apple limitation)
- Recommended: Vgate iCar Pro BLE, Veepeak OBDCheck BLE, OBDLink CX / MX+, Repair Solution
- Avoid cheap clones labeled "v2.1"; they often drop connection

TRY BEFORE YOU CONNECT
Demo mode lets you explore every feature without an adapter.

Available data depends on your vehicle's ECU; some cars do not report every sensor. Never operate the app while driving. The developer is not responsible for any damage resulting from use of this app.
