I have a Droid smartphone and use the Sparkpeople app and Sparkpeople.com (all free) to track my weight (provides a nice little graph over time), and have used it in the past to track my food intake with decent results. The only caveat is that the foods listed are a wiki, like Livestrong, so you need to have a general idea of what you're consuming anyway lest you accidentally chose an inaccurate nutrition profile out of the list of possible choices. You can also chose your favorite meals and foods, and create food listings of your own.
My favorite feature within Sparkpeople is that you can customize your desired daily goal macronutrient ratios within the free membership (protein/carbs/fat), which is something that it looks like Livestrong won't let you do unless you pony up the $45 for annual gold membership. You CAN see your ratios consumed that day in Livestrong; you just can't change your desired goal ratios for a basis of comparison, so within a free membership Livestrong analyzes your macronutrient intake against the standard 2000 calorie USDA recommendations.
