track car performance with the iphone

[mohrt]

For those of you with iPhones (or iPod Touch), here's an super useful app. It keeps track of 0-60 Acceleration, 1/4 Mile Elapsed Time, Lateral G's, Horsepower and more, and all you have to do is set it on the dash. Cool It's a mere $12.99 USD from the app store.

No, I'm not affiliated with them.

From what I'm reading, it gets all of its data from the accelerometer (no GPS involved). Therefore, it gathers input from acceleration/deceleration and time, and from there determines velocity. Therefore, it makes me believe that it is very accurate with short lengths of straight-line speeds and times, but around a track it would not work well, if at all. You can zero the speed at any time to meter your lateral G's, but I doubt that helps much around a track.

I've been toying around with the idea of building an app similar to this, but also includes the GPS tracking so you can watch yourself go around any track from a satellite map.

Yep that's right, you can download the SDK. All applications are written in Objective-C in the OS X Cocoa environment. To submit applications to the App store, you must first apply for a developers license, which is $99 USD per year. Once Apple accepts you, you can submit applications, and they are put in the store once approved by Apple. The price is determined by yourself (.99-999.99), and Apple takes 30%.

There is a microphone on the device for sound input.
