What else can Carly do?

Used Car Check

All control units are read out and compared to check whether someone tampered with the speedometer.

In-Depth Diagnosis

All control units are analyzed, and the error codes are read out. The analysis corresponds to the manufacturer 's quality.

Lite vs. Full Version

You can try out the different features, and test the compatibility of the Carly app with your car model using the Lite Version.

A single car diagnosis at the workshop costs anywhere between 60$ and 100$.  Purchasing the Full Version of the Carly app will perpetually save you these and other costs at the push of a button.

With the Lite Version you can test the compatibility of  each function for free and find out if it will work for your car model, before purchasing the Full Version.
