I just started using Daily Burn recently (http://dailyburn.com) and it seems to be the first food tracking system that's been designed to be easy enough to actually continue to use, but powerful enough to be useful. I downloaded the scanner application for my iphone, and just love the ability to scan UPC codes have food data available.

Anyone else tried it, or figured out a way to tie it into other programs, like make it pick up info from WKO+ or Poweragent?
