It does work on other cheaper phones if you read the fine print :-}

Yeah, and my iPod Touch! Whoopie!
I still don't get how it works w/o GPS, beside very elaborate/speculative deductions using the accelerometer.
I want to buy it, even though I'm just about to put the bike away for the season...
Anyone on here have it?

If you check it runs on other phones including my old LG cheepo phone (100uk Pounds) you do have to look but it does.
And if you do have a good phone you can have GPS for speed logging too so that if you find a nice quiet test road you can set up cones etc in EXACTLY the same place and do rolling starts (recommended for bikes since wheelies tend to fool the accelerometer )

In the movie he says he had to re-set the gizmo as the pre-stage burn out re-set the darn thing. also the Iphone worked as a phone as someone called him which screwed the program as well.

George thats a good hit.

I plan to get one and save myself a bunch of money. I was about to go to the dyno next week. Hoping this will solve that.... but how to do. Just go fast on the track and then check the results?

Thats sweet. I need to figure out if I can set it up on my HTC Tilt. I hate the iphone.

Steve,
The consensus is that you use GPS to set up a straight line start & stop & then launch the program & the bike.

Wheelies screw the readings for acceleration recording and to some extent corners, tight kneedowns being worse

But according to the video test by the drag car guy it is extremely accurate in what it does. If you go to the programmers site there is alist of phones it works on but it is not easy to find as I figure they did a deal with Mac & their naff phone for publicity
