Here is a short demo of Rev2.0 on my Ipad:
If I had to rate this app, I would give it a 4 out of 5. It has a very basic skin set that you can only customize by a few color changes. You can monitor 5 metrics at a time and choose the layout as you see fit.
Highlights: Ability to record and email file to analyze
Track day function
Ability to read and clear engine codes
Wifi connection is very reliable(using PLXdevices kiwi device) and very little signal delay
Lowlights: Lack of customization
Somewhat limited number of actual metrics to monitor
