OBDLAD: OBD2 Car Scanner

Turn your Android phone into a practical view of the OBD-II data your car makes available. With a compatible ELM327 adapter, OBDLAD helps you check diagnostic trouble codes and watch key readings as they change.

Start with diagnostics
Scan stored, pending, and permanent DTC trouble codes in separate views. Review detected codes and the details available in the app before your next repair shop visit.

See what your ECU supports
Monitor live vehicle data such as speed, RPM, coolant temperature, engine load, control module voltage, fuel-related values, and other available sensors. The exact set of readings depends on the vehicle, ECU, and adapter.

Choose how you connect
Use Bluetooth Classic, Bluetooth Low Energy (BLE), or a supported Wi-Fi ELM327 connection. A demo mode lets you explore the interface when an adapter is not connected, while metric and imperial units keep the dashboard familiar.

Go further with Premium
Premium unlocks DTC clearing, local DTC history, live sensor graphs, dashboard customization, full-screen instrument layouts, and the map-assisted Premium Cockpit. DTC clearing depends on vehicle support and should be used after the underlying issue has been addressed.

Compatibility note
OBDLAD is an OBD2 diagnostic app, not a standalone scan tool. Vehicle communication requires a separately obtained compatible ELM327/OBD2 adapter. Available codes, PIDs, and live readings vary by vehicle.
