Much improved since update


Used this for a number of months and it’s been very useful.
Then there was an update which stopped all communication, but they’ve fixed this issue and it’s working well now.
Useful paid app that has helped with a number of cars and issues.

Stepped up


I changed phones and was asked to pay for the functionality I already had. Once the developer found out they told me how to get functionality back. Great customer service. I use the app often and I’m glad I got it.

We made a video available on our Youtube channel to help you :

The restoration of the Basic / Plus Edition of EOBD-Facile is only possible between same brand's OS (iPhone to iPhone or Android to Android).

WiFi version.


Don’t know if there connectivity issues with other models but I’ve had a really difficult time connecting with the WiFi version. My mistake when buying as I thought I had selected the Bluetooth version. Have only been able to successfully connect a handful of times (let’s call it 1 out of 10 attempts).
