I have both a laptop with wired plug to port for doing the heavy lifting and major diagnostics.
I also have the wireless plugin adapters that work with phone apps. I leave them in the glove boxes or center consoles.
This is a whole lot better than pulling the laptop out just to check a code. Also when rolling down the road and my big scanner is at the shop does me no good.
I have 3 apps mainly because some work better than others on different brands. But the adapter works on all my current cars.
I have one of the adapters in my daughters car so I can just have her plug it in and walk her thru which app to use. She sends me the screen shot and I can remotely trouble shoot.
I search thru all the forums to find out which ones seem to have the least issues. (jeep forums, gm, kia, this one a few other older truck sites etc).
There are lots of them on amazon at all different price points. Once I have the one that works well with the right car it just stays with it.
