MyFitnessPal is a must-have app for those looking to keep better tabs on their health. This handy app lets you keep track of your calories, scan bar codes of food items and add meals to a food diary. You can also view your nutritional intake (cholesterol, sodium, carbohydrates, etc.), track your weight loss progress and add set up reminders for exercise. MyFitnessPal for the Galaxy Gear boasts almost all of the same features of the regular app — scanning bar codes, tracking calories and adding food to your diary — with the added benefit of a pedometer.
