Yes, it's a great "beginners" program. I used torque back in 2010 when it first hit the market, there are other "free" apps out there too (rev2 and dashcommand as I previously stated) ... no harm in downloading each and playing around to see which one fits you best. I had high expectations when Android tablets hit the market, but was disappointed when torque/rev2/dashcommand would get very slow on display updates when you added more than like 3-4 gauge displays (even considering the tablets faster processor and more screen real-estate). I think most every of the "apps" are free to download, at least in "lite" editions to eval, (even dashboss can be loaded on your iphone or ipad to compare) but generally are useless until they're mated to a functional and compatible supported bluetooth dongle. It's cool to eval interfaces though, go for it!!
After eval'ing all of that for some time I worked my way up to dashboss and am impressed with the external inputs and extended PID's it supports on the g8 platform. Dashboss is only apple, and it's the only apple bluetooth stack approved in the apple store (because it's encrypted bluetooth which apple requires, Android does not have this requirement... thus why there are "commodity bluetooth transcevers).
No ill will to getting your foot wet with this solution, and I can't wait to read the review on it maybe even with some screenshots. But my wideband is datalogged with 11 other PIDs that I can choose at anytime, and that's what works for me.
Good luck OP
