I played with it a little bit yesterday - but could not do a "real run". It told me I used about 142 hp. Just FYI - you can hit the power button and the "home button" together to take a screen shot -> it will appear in your photos -> email it to yourself - and post here!

I am most interested in the 0-60 function... My father and I are in a debate this week who is faster- his clk500 or my 996, haha.
A pre-curser ruling with a "dyno" would be great before taking it to the track

Subscribed, I'm looking for opinions of how well this software works. It's a lot cheaper than a Gtech and far more practical if it's decent.
The reviews on the Apple Store are mostly positive and the accelerometers on the iPhone are pretty sensitive so I could see it being a decent product. It's probably worth a shot for $13.

That's not really bad if it's consistent. You could determine if mods to the same car are effective. Maybe not as good as the Vbox but not bad for the price.

GREAT FIND!
Well, surely you get what you pay for - its not going to be the gold standard for measuring performance... but it seems pretty decent. As Dan stated - if its consistent, you could at least evaluate different mods.
I had to go back into work tonight - stopped first at a light with NO traffic, I pulled it out quick... but my "secure" mounting allowed it to FLY back into the rear seats. It did record >2 G acceleration though... lol! Wait... this is going to be terrible for my clutch.

Interesting note about rollout:
1 foot rollout lead to a .34 sec lower figure. The difference between the two units is close to that .34 sec difference, with the iPhone being the higher value. Does the iPhone also reduce the value by .34 secs to account for a rollout? Is this actually a more realistic value than the Vbox?
