A free demo version is available at our web site: www.Calorie-Tracker.com. The NutrAssistant Calorie-Tracker System is an easy to use application for tracking your nutritional intake, on a daily basis. There are hundreds of pre-loaded food items in easy to use, drop down picklists. You pick your target caloric intake for the day and Calorie-Tracker calculates the percentage of your goal that each item selected will give you. Each pre-loaded food item includes actual calories, the calories as a percentage of your daily goal, and your protein, fat, and sodium as a percentage of your RDA requirement (based on your daily calorie target). You can delete food items you have no interest in, as well as add your own food items, allowing you to create a custom food system, to meet your tastes and needs. There are eight food categories, including snacks, fast foods, and your own personal recipes. You can create your own recipes from food items in the system, which you can then select the portion of your recipe that you want in your daily diet. There are automatic conversions to change across different units and numbers of units. There is a handy unit conversion for dry and liquid measures available from the drop down menu.
