A personal trainer in the palm of your hand

You get a call on your cell phone. Your personal trainer wants a report on your physical activity today and what you have been eating.

In short order, you get feedback on how the exercise you've logged fits with your goals for the day, and on how much you have left to do, with suggestions for how to meet your goals. You could even get an assessment of the nutritional value of your diet.
