The award-winning AthleteInMe's Calorie Converter app helps you make better choices when dining out by telling you exactly how many minutes you'd have to exercise in order to burn off menu options. Simply enter your body weight, then select from nearly 3,000 items including Starbucks drinks, fast food, and even beer. You'll think twice about ordering that chocolate tarte for dessert when you learn that you'd have to walk a marathon to negate it.
Available for: Android, iPad, iPhone, iPod touch ($2.99; athleteinme.com)
