It's easily one of the most detailed diagnostic tools on the market and it's under $110 for both the cable and the software. Easily does everything my brothers $1500 OBDII scanner does.

I don’t like any product that relies on a phone app to work because their app will become obsolete after a year or two and you’ll have to waste time trying to figure out a new solution to get it to work.
