I have used Ascendo Fitness Assistant for several weeks, I use it to calculate my total calorie intake by using entries already included in the database, you may also add new entries, Ascendo provides a desktop companion with thousands of nutrition items that you can copy to your BlackBerry. Next I enter my daily exercise routine and then Ascendo Fitness Calculator tells me how many calories I have burned for the day, then I can track my progress and use the option to enter my daily weight. Ascendo Fitness did a great job of calculating my daily calorie intake..., total calories burned, the application also has several calculators to calculate your healthy weight, ideal weight, body mass index heart rate and finally your basic metabolic rate, these are calculated by entering your personal settings such as your height, weight, gender and age. This application is truly one of the best fitness tracking application that I have encountered.
