I use Myfitnesspal.com as well, and I have the app on my Droid X. I love it. At first I just wrote down everything I ate in a notebook, but this is soooo much easier. I love being able to track calories, protein, carbs, sugar, everything, and you can go back to any date, even look at graphs. It also has a thing where you can scan barcodes and it puts the info in, I have only come across a few foods that it didn't find.
