A Free program for Android‚ by FIXD
If you have a car but do not understand how exactly your vehicle works, you must download and install the FIXD. This is an application that helps you figure out your vehicle by translating check engine lights and tracking scheduled service.
The FIXD tool describes everything about your vehicle in Layman’s terms. This means it lets you understand better what the problem is if you encounter one. If your car experiences sensor failure, it means MPG is reduced, and it may not pass emission tests.
This app also notifies you when the car needs maintenance. In addition, you can create records for services.
