I found a good calorie counter back a while ago when I was reading CRON blogs (caloric restriction, optimum nutrition). It works as well as fit day and no subscription required:
Its open source and very adjustable. Since I am having trouble getting back on the low-carb wagon, I am logging my food choices in the Cron-o-meter and trying to stay under 2000 calories. I can hold nicely there without gaining, while I try to slowly go back to reducing carbs. Oy, tortillas! Oy, bowls of fruit!
