What it reads

Subaru-specific data, not a generic OBD clone.

The free version already includes CVT oil temperature, CVT ratio, AWD duty (%) on a gauge screen, and trouble-code reading. A full-version subscription adds extra parameters, graphs, and logging (premium adapter required).

CVT oil tempTransmission heat while driving or towing — the readout Subaru owners look for.
CVT ratioLive pulley ratio from the TCU, not a generic OBD PID.
AWD dutyCenter-clutch duty with a chassis view of how torque is split.

Gauge screens

Analog-style arcs for speed, RPM, coolant, oil, MAF, fuel, VDC wheel speeds, and more — arranged the way you want them.

Trouble codes

Read and clear DTCs with history context across modules — airbag, HVAC, meter, and more.

Graphs & logging

Plot live traces such as RPM and speed. Logging is available with a premium-level adapter in the full version.

Bluetooth 3.0 & BLE

Connects over Bluetooth Classic (3.0) and Bluetooth Low Energy (4.0).

Requirements: Subaru vehicle MY 2012+ (OBD CAN) and a compliant adapter. Premium-level adapters give better speed and stability; some features such as logging expect them.

* OBDLink CX: pair and connect within 5 minutes of powering the vehicle on. If you run into issues, try downgrading the adapter firmware and upgrading it again. ** Firmware incompatibility with certain smartphones (such as Pixel 6 and newer) can cause Bluetooth connectivity issues.
