This is quite a good program. It does what it says it does, namely track the foods and drinks you consume every day that have calories in them. In doing this, it sheds lights on what you are eating and in what ratios. It sheds light on the situation and that helps you manage your weight.
This program has an extensive and excellent database with most foods you'll run into listed in it. This includes frozen entrees from most major companies as well as some restaurant food. However, you can always add your own food products to its database and record your use of them.
The UI is not perfect although it is more than passable. For example, to delete an exercise line-item, you have to click the delete key, you can't just hit backspace as or delete as you would with most programs. You should be able to copy-and-paste items between days -- it's annoying that you can't, although the vendor would probably suggest using the "create group" feature. That's right, you can create a group of foods and name it something, like "chicken sandwich with cheese and wheat bread." Groups can't contain just one item, though, so I'd really still like to have copy-and-paste.
Speaking only for myself, I find this product is most useful if I have a computer in my kitchen that stays there all the time. (Or if not the kitchen, then wherever you do your eating.) That way I can enter the food as soon as I eat it, know exactly where I am for the day, and if I make a decision that costs me, I have to make that as a conscious choice right then and there rather than kind of blundering along not really knowing how much I've eaten. This ties the decision and the consequence closely together in time, which in my own case has been very helpful.
Again, I paid for this product, I think it's very much worth it, and I give it an A+.
