Scangauge 2 or Ultragauge ??

I do, it works for me. Matches the dash better, cheaper, larger display has many features that are useful. You can make your own default front display of your choosing.

One Diego to another, grew up there! (Clairement Area)

 

I have the UltraGuage. I actually bought for my Odyssey but tried it out for awhile in the Prius. It does have a nicer display and is a bit less $. My gripes are that it doesn't read the fuel sender level, nor does it read battery state of charge and temp. If I'm wrong, hopefully someone can tell me how to correct it. Other than that, it was useful to monitor RPM and coolant temp. At some point, I'll probably try out the Torque app instead.

 

The temp displayed is only the engine. It doesn't read the traction battery nor inverter temp to my knowledge.
