The Analysis screen provides analysis of the current day. You can perform detailed analysis of your weight goals, and plan your diet on the Plan page on the web site.
If you consumed enough calories (more than 1,200), the top section - Daily Analysis - analyzes your day from the calories perspective. The equation displayed at the top calculates the total daily calorie loss based on your current weight. As you start losing weight, your body needs fewer calories, and this screen takes that into account estimating actual calorie loss for the day.
Remember, to lose a pound of fat, you need to lose 3,500 calories (not within a day, but in the course of several days).
The second section - Day Highlights - analyzes your eating patterns and individual nutrient consumption.
You can navigate between dates by tapping the arrows at the top part of the screen. To quickly return to Today's date, tap on the date.
