Program works for me. One of the few things is the brevity of the food database, which is nice so that I can add my own food items, however, a link to a good calorie estimator for foods and exercise somewhere on the web would help. to me 3 days is a short period to try a program. Maybe a week or 2 since the goal is to lose weight. In using a program 3 days most likely you aren't going to lose weight. Success with the program would make you more likely to buy it.
