Has anyone used www.mynetdiary.com?

Hi there.  I am looking for an alternative to pen and paper to track food intake etc.  Have this fancy new phone and wanted to use an application from it.  Has anyone used this either on their computer or smart phone?  Appreciate your insight.

I use MyFitnessPal.com There is an app for iPhone, Android and maybe Blackberry?

I've been logging my food since Feb. 2008 and I think it's really helped me.

Thanks. What all does it track please?

It's got a food diary that you can customize somewhat. Then, you can put in your exercise and it estimates the calories you've burned. You can also log your strength training (sets, reps, weights) but I don't do that.

There are also some tools (calculators) and a message board.
