What app is useful with the micro mechanic mechanic device?

Hello sylvestre240,

Thank you for using Apple Support Communities.

If you are referring to the Micro Mechanic device to read the check engine light on your car there is an app by the same name, Micro Mechanic app, that the device instructions indicates you need to download.

If you are referring to a different device, you would be best served to contact the manufacturer of the device to see what app they recommend.

Best regards.

I am trying to find what app I can use for my micro mechanic engine light check
