Okay, here's my quick review, for those who want to learn more:
Downloaded the app, it was free.
It talks bluetooth, which I imagine is the device on the other end that is required to be purchased.
Can be ran in demo mode.
Main menu has tuning, dtc, maint minder, mileage mentor, daq, gauges, inclinometer, and one touch. Looks interesting, the graphics are nice.
The maintenance minder "service" that starts on the android phone allows you to record mileage and what was done, etc. Maybe this syncronizes online somewhere where you can keep your maintenance records online or in printed (archival) form.
The mileage mentor (at least in demo mode) looks like a graphics equalizer, but has a "smoothness" graph, that smartly, starts "burning money" (a 20 dollar bill "specimen" is shown to be burning, which makes sense I suppose) ... that is probably more for the prius owner, not the g8 owner
The DAQ setup looks like a cluster of nice looking bargraphics,4 pages worth.
The gauges setup has some options, looks like a carbon fiber "superchips" digital gauge.
The inclinometer works without the bluetooth (and in demo mode) and could be useful for recording the "lateral G's" in a controlled environment.
The one touch is probably a prepriotory app that allows it to give a diagnostics report on the car in question (that is hooked up) and it warns that it could take up to 15 minutes to complete. Unsure of function, I did not go there.
Overall, a slick interface that has some potential.
I'm glad I downloaded it, and I would be interested to hearing the price of the "gateway bluetooth ODB2 module" that is required with it, or if the amazon bluetooth ones would work or not.
I recommend anyone with an android phone and the google app "Barcode Reader" to scan the 3d barcode to install the app.
After installation, it is called "Vivid" on the android programs list.
Try it out, it's neat.
Will explore more soon.
