I am making a 7-10 slide presentation on the topic of "Vitality: Fitness and Nutrition Tracker" app. This is a startup app that tracks your calories, suggests you a diet based on your body type, and also gives you excercises based on your goal and body type. I need a problem and hook statement, target audience, solution and selling point, how this app can make money ( subscription and static ads ) and how will the business grow?.
