I purchased Dietpower last December and am very happy with it. I had been using Dietwatch for years but it finally conked out on me.
With Dietpower you can add foods, create recipe, track your weight, track your exercise and track about any other nutrient you can think of. They have a 15 day free trial. I prefer it over Fitday because I don't have to be online to enter my foods and I don't have to deal with slow connection speeds or the occasional times when the site is unavailable.
The URL for Dietpower is www.dietpower.com
if you are interested. I used it for the 15 days before I bought it to try as many things as I could. I think I paid 50.00 for it and for me it was worth it.
