Two skinny J's
Yet another app to try. Looks like if you have an iPhone ( Hack did a write up on it a while ago)you could use it with of those fancy smacy ANT devices with for heart rate and cadence I suppose. Gonna give it a whirl on tomorrows ride. I even check the setup before I use it this time since I don't want it twittered of facebooked (really? Is that a word?) with the dreaded mile by mile FB updates again. Looks like it has plenty of potential.
