Measure 0-60, acceleration and more with your iPhone

[Pedro-bot]

a new app called Dynolicious works with the iphone to give instant feedback to measure performance. Anyone here tried it yet. For $12.99 I may just give it a try.

for $25 i could run a few quarter miles at my local drag strip track. That would be more fun.

The new iphone has that tilt sensor, thats probably what it uses to measure this stuff. How accurate is it? Buy it, go to the strip, and trap yourself for 1/4 mile and see.

I think it does the HP calculation based on your cars weight (which you will never be able to measure since you probably threw in anywhere from 100-500 lbs of extra crap) and the time to travel x miles at y speed. is it accurate? probably as accurate as the numbers you give it which probably inst that accurate at all. better of with a video camera aimed at your dash.

OR, it uses the GPS, which then its probably pretty accurate.

I'm sure it uses the GPS, it might use a combonation of GPS and the tilt sensor for skidpad if it does that.

However, I've found the GPS reciever on the iPhone is really sluggish.

I don't think it uses GPS. What I've read so far says it uses the accelerometer for this.
