TIL those cheap Bluetooth OBD2 scanners from the auto parts store actually work pretty well for basic codes.
I was convinced they'd be junk, but my buddy's $30 unit pulled the same P0420 as my shop's $800 scanner on his Civic, so what specific jobs have you guys found them actually useful for?

Wait, can't you pull live data with the right app though?

Nah, I've had the total opposite experience. My cheap scanner read a generic P0300 misfire code, but the real shop scanner showed it was specifically cylinder 4 and had live data pointing to a bad coil. The cheap ones just give you the basic code, not the actual info you need to fix it. For anything more than clearing a check engine light, they're pretty much useless in my book.
