The Fixdono is a compact Bluetooth 5.0 OBD2 adapter that plugs into a car's diagnostic port and pairs with a phone app to read fault codes, live data and I/M readiness. Its main draw is the app with no subscription fee, which sets it apart from brands that charge for advanced functions. It covers the standard OBDII protocols, so it works on most cars and light trucks from the mid-2000s onward, but it is a basic reader, not a bidirectional tool that can run tests or reset modules. It suits DIY owners and used-car checks rather than professional diagnostics.

With 50 ratings averaging 4.2, owners see it as a cheap, no-subscription way to read codes and clear a check engine light. Complaints center on the app and Bluetooth connection rather than the hardware itself.
The Fixdono OBD2 Scanner is a compact Bluetooth diagnostic tool for cars and trucks that support the OBDII standard. It plugs into the vehicle's OBD port and works with a free-to-use app on a compatible mobile device. The app has no subscription fee, and no binding or personal information is required.
It reads and clears diagnostic trouble codes, shows live data, and checks I/M readiness. It also reads vehicle information such as the frame number, battery voltage, freeze frame data, monitor test results and MIL status. A performance test covers acceleration, braking and distance.
After the scanner is plugged into the car, turn on the phone's Bluetooth and start the vehicle. The scanner pairs automatically. If it doesn't, open the app, choose "Connection settings" in the upper left corner, find "Bluetooth LE" and tap to connect. The phone's location permission must be allowed. If the engine light stays on after clearing codes, turn off the engine and clear the codes again with the power on.
