smart phone apps
 

Hi, I'd like to get an idea of what's available for iphone and android and your experiences using them before I make a decision on my next phone:
apps I'm looking for:

camber gauge
g meter (with logging prefered)
lap timer with video, gps and obd2?

TIA

I'm about to try Harry's Lap timer on the 20th at Palm beach International Raceway. Will let you know how it works out.

Any level should work as a camber gauge. Whether they are accurate and precise enough is up to you.

Harry's Lap Timer is probably the most popular. I think it's only available for the iPhone but soon will be available for Android.

I use track master for my Droid. Does pretty well, but I just scratch the surface of everything it can do.

If you want something simple and free for android, I'm using Race Chrono:

I use Solo Storm... but you pay for it. becoming very popular in the AutoX Scene..

I'm pretty happy with Harry's Lap Timer so far. I haven't tried the apps video capture just yet, still looking to find a decent phone mount.

Trackmasters and torque on the droid.

Should I get Trackmaster or Harry's Lap Timer? I have a droid. Anyone use both and can recommend one over the other? I'm also thinking about the Torque Pro app and using that and selling my ScangaugeII. Or should I wait until the fancier versions of Harry's Lap Timer come out on droid that are already out on Apple?

RaceChrono + Qstarz GPS
 

I'm using RaceChrono, and like it. I also picked up a Qstarz 818xt from Amazon (~$90 or so). The stock GPS in most phones samples at 1Hz. With the external GPS you get 5Hz or 10Hz (depending on how you configured it).

It was a little bit of a pain to get the GPS to work with my phone, but I've used it now with both a Galaxy Nexus and a Nexus 4 without problems. Might try the Nexus 7 next time.

Sample data from the built-in GPS:

And from the external GPS:
