While Fixd does have its limitations, and there are some vehicles that it will not work with, it is a useful tool for anyone who has ever wanted to know more about what's going on under the hood of their car.
Fixd works by tapping into the onboard computer in your car, reading information that’s stored there, and relaying the information to an app that you install on your smartphone. It’s similar to generic ELM327 scan tools that perform the same basic task, except that the sensor is designed specifically to work with the Fixd app.
If you want to get the most out of Fixd, you need to buy a Fixd sensor and install it in your vehicle. You can buy these sensors from retail stores like Walmart, and online stores like Amazon, or you can buy directly from the source by downloading the Fixd app or visiting their website.
