iAutomotive iphone app - opinions and experience?

[visionary]

Has anyone used the iphone app "iAutomotive"?
In particular the section on frontal area, cd, power and speed looks like a useful and simple calculation tool, but before I put too much faith in its answers I thought I would ask some of you experts if the "maths" is accurate.
I'm hoping its reasonably accurate, as I've used it as the basis for calculations on my project vehicle.
Tell me what you think!

Bump...

I'm searching the forum for iPhone apps right now, but I'm not seeing anything that looks like it's worth it. Has anyone installed an app that helps automate tracking or do something useful? My focus has Bluetooth built in...

If you are looking to track mileage there are several out there. I'm on an android and use one called FuelLog. I liked the free version so I bought the paid. When I like an app I tend to buy it. It encourages the developers and often gets extra features. With this app it the paid version allows tracking of other expenses and multiple vehicles.

I have also been using my tracks for gps info such as altitude and speed tracking. It seems to work pretty well but I have had it glitch when I forgot to shut it off at the end of a trip. I sat still for three hours and it showed I had traveled an extra 700 miles with a top speed of over 400 mph. I think my tracks is a google app. I'm not sure if apple has something similar.
