I'm not even going to read the 11 pages-- I have the app and love it.
I have the $5 torque app (way better than the lite) and two Amazon.com
cheapo bluetooths (one for the tool box, one for running around) and for a more 'permanent' mount, an OBDlink MX because a) doesn't constantly ask for the pin like the Amazon/Ebay
ones and b) has a sleep mode not draining the battery when sitting for long periods of time.
A bonus for the paid torque app, it has the PID to watch auto tranny temps in the 1st gens (at least my 2001). I have a HUGE HUGE ass hayden and my temps still got really high when driving through GMR on the way to some off-roading. Good info to know, maybe its time for a rebuild, or a different cooler configuration (ducting, remove OE cooler from series connection etc).
