I joined the Fitbit craze and strapped one on early in March. I committed to wearing it for the next year. Upon recommendations from family and a friend, I also linked to the apps MyFitnessPal and RunKeeper. I'm not particularly great at wanting to keep track of everything I eat, but it helps to do it for awhile to get an idea of the calories I eat. I particularly like RunKeeper as it tracks my walks, gives me a pace, and plays music. It is a good motivator.
