Another really good App Ive been using has helped me lose weight. Its like a diary App that you put in your foods and give you the approximate caloric amount and it marks down how much exercise you have done (like a fitbit).
Ive lost 15 pounds in the last 5 months with this app as I am now able to track my calories better (I was not Obese and didnt need to lose as much weight as others might) . I actually use this app alot more than Waze, which I only use if I am in an unfamiliar area or stuck in a traffic jam and I am trying to figure out how long the jam is.
