I love my fitness pal. SO easy, and it has by far the largest food database I've seen on any online site/app. I haven't had to manually enter a single thing after using it a week, it has the recipe calculator, and you can save meals you eat frequently on there so you don't have to enter the individual components.

I have an iPhone, and from what I understand, the Droid has the UPC scanner but iPhone doesn't. That's the only thing lacking, imo.

I use Lose It! and I think its pretty awesome.

I'm so glad this thread got started- I'd become so frustrated not being able to find an easy app to track calories. All of your suggestions were very helpful and I've downloaded a few to see which I'll like the best.

I like using my fitness pal too and the scanner, it could be better, but love having something on my phone, for quick reference too I have a Droid.
