Heart rate you'd need some sort of bluetooth monitor. GPS should be able to give you everything else, except crank speed.

Here ya go. They even make a plug in unit for crank sensor and HR monitor.

I don't yet have an iPhone but am considering it. I read about the 'tethering' issue but don't even know what it is ? It sounds impt. to most of you guys...

I want an iPhone program and attachment that will plug into an O2 and RPM sensor as well as do data logging.

James? Where? Is there a link? :confused:

dd74... I too am interested in this app, found a lot of good ones, distance ...but no crank sensor or hr, I will be ordering this phone, I still have 2007 model and have been waiting for this, I skipped the 3gs( my wife couldn't resist) .... can't wait

My two go-to apps:

iReal Book

TC Electronic | PolyTune iPhone App

iPhone Cycling Applications «

There ya go. Calm down. Everything will be oooo-kaaaaaayyy...;)

Very cool. Now, how does one mount the iPhone to the handlebar stem, and sweat proof it?

Yeah, mount the iPad to your handlebars.

Sweat proof? I use a ziplock bag!

Hmmm...and I already have an iTouch. Cool. Thanks.

OH Geez. Am I talking myself into buying an iPod Touch the next time they are on Woot?

Must resist...Must not buy Apple product...the light is growing dim...

Can the iPod Touch play music and run another app at the same time? The 32GB unit, refurbished was only $229 on Woot a week ago...

Does the iTouch have GPS?

See the innovate site:

Innovate Motorsports OT-2 - Transform your iPhone or iPod into a wireless gauge, data logger, dyno, efficiency meter and OBDII scan tool.

Unfortunately OBD-II only. The regular version is $350.

Yes

No, seems not. But the wifi feature in the iTouch seems to pick up signals that can track where it is.
