I'm sure you'll get class credit for any app, if you want an app that actually works, read SAE#810186. I discovered that the way people "calculate" Cd through coast tests is very flawed. I have this paper, and was preparing to make a thread about it soon.
I'm aware its flawed because at highway speeds drag can account for a wide range of the percent of overall drag experienced by the vehicle and accounting for that is tricky. Thank you for the paper. I'll take a look at it here soon and hopefully can get something figured out.

And could I possibly get access to that SAE paper? If you have a digital copy or something that would help.

And unfortunately I'm on Linux so I can't develop for iPhone just yet.
