it only needs to be hard mounted if you intend on using the accelerometer features, you don't need anything special for the GPS.

Originally posted by Lof8 View PostThese apps look really cool. I hadn't even considered this before. Harry's Timer looks very thorough, but I cant seem to find a list of the programmed tracks.
In fact, the navigation takes some getting used to because of how much stuff is in there. That said, I haven't used it ON a track. But I've made a few tracks out of local roads, and it functions pretty well.
If you wanted to know if you were shaving fractions of a second off your laps, it probably isn't good enough for that. If you wanted to know what kind of force and speed you were putting through a corner, it will tell you that with a great degree of accuracy.
There is a track list out there someplace. It's not easy to find. I think I google searched for it to find it on his site. The track list is HUGE though, and always growing. Also, because you can make a track (though it's not simple) you could always map out your local track.-------------------------------------------------

Originally posted by NigelStu View PostBeing very familiar with GPS based data acquisition systems, I'd be very curious to see how these phone apps compare. I have a hard time believing that the accuracy and processing power is anywhere near the level of even the low-end DA systems, so doubt the usefulness beyond 'look how cool this is, I did a lap in x.xx.xxx!".
I have an Android phone, so I can't compare the Harry's timer. Anyone with a Traqmate or Race Technology and either Harry's or Trackaroo want to compare output between the DA system and the phone app?
I know that the sensors in the iPhone 4 are very sensitive, almost unbelievably sensitive. The GPS is a GPS, it can only get better by getting better readings. I do know that external GPS receivers are suggested for the iPhone 4 by the software developers, if only because the receiver can be mounted someplace where you wouldn't want or couldn't mount the phone.-------------------------------------------------

I used Chronos GPS for Android and it worked well on my HTC Thunderbolt. It drains the battery pretty quick though (Thunderbolt already has short battery life). I ended up plugging the in-car recharger while I was tracking.
I used the free version which doesn't let you export the data. The registered version lets you export data. Also, this app is accurate only to the tenth of a second.

I have the GPS Lap Timer. Its $1.03 on the android market. You use a satellite photo to designate the start/stop location and it learns the track from your first couple of laps. The only problem i experienced is there was no 3G reception on the track to obtain the satellite images. Had to set a generic location based on GPS location and then i went to fast food place and used the wifi to download the track GPS image and refine the stop start location. So basically i'd recommend trying to set up the track location and start/stop position before you get to your remote location.Your signature picture has been removed since it contained the Photobucket "upgrade your account" image.
