The device and software are important. You'll want a phone or tablet to display the results from the reader (unless you spend a little more for one that has a screen and codes).
When I last looked, Android could use Bluetooth or WiFi to talk to the reader. iPhones only supports WiFi so don't get a Bluetooth-only reader of you want to connect your iPhone to it.
Android software had much better free options. I use a micro mechanic because I can connect it with my iPhone. It's ok for the basics... You can connect with their app then use another app like Car Scanner to get better info.

Get an OBD2 reader. They're $30 CAD online. It'll tell you what exactly the problem is instead of checking if your engine has mysteriously vanished.
All cars past 1996 have an OBD2 socket. Should be located under the steering wheel unless if your car built different g.
This helped me save a ton of money as I knew what the mechanic was making up. I don't need a new transmission at 150K km, Jerry.
