What phone apps are people using to track food intake and exercise ? I'd really like one that can track my protein.

I use myfitnesspal.com - I love that it has a pie chart option with carb, protein, and fat designation so I can see how I've eaten for the day. Great phone app and easy to use online as well.

I second myfitnesspal I especially like on the pie chart and goals that I was able to customize my macronutrients because they automatically have high carbs in their program. I've learned so much about nutrition just by logging all my food (if you bite it, write it haha). And the little pat on the back they give is nice when they notice your weight loss.

I too use MyFitness Pal. I like how it syncs with FitBit so I always know activity levels and nutritional information. The iPhone App will sync with the iPad as well
