I've been using them for years. Back in my Audi I had a tablet that was running android and using the OBD2 Bluetooth Dongle (ELM327, $8.49) for track days. I didn't want to clutter the dash with gauges. This let me customize it using the app (TorquePro, $5) and read everything from AFR, to Boost, to Timing, to Fuel Rail Pressure (direct injection car).

On my truck it does a good job reading and erasing codes, but there's a lot less CAN based sensors. I've got a 2010, I'm guessing the 2013 jump probably introduced a lot more CAN based messages.
On a 6.0L you can even read injector pulsing.
And you can even enter your own sensors if you know the CAN message and they're not already loaded on the app.
