An app for dieters and fitness buffs. Tracks weight and calories, carbs, fat and protein consumed and calories burned by various fitness activities. Contains data for many foods and activities. You can set up a personal list of your foods and activities so you don't have to search through the whole database to add an item. Does analysis and displays charts showing you progress. A couple of menu items (meal and activity plans and "circle") don't work as they rely on a server that's currently (probably permanently) down.
