I have downloaded and tried a number of the diet/exercise applications for the Mac. I'm a long time user of Calorie King's Nutrition & Exercise Manager. This company is not very responsive and has done little with their application in years. They don't seem focused on Mac users. Their database for food and exercise is (to my shock) better than any of the new applications I tried. I also tried Diet Controller and Weightmania. Both seemed to complex for my simple tastes.

The main problem with "Perfect" Diet Tracker is that their food and exercise databases are lame. For example, I grab breakfast at BurgerKing today, but PDT's database has only a handful of BK's menu offerings. I had to go to the BK website to enter the meal manually. I can see that I will only like PDT if I build my own databases. Hopefully, like other products I have tried, my custom databases will not get overwritten by a future database update. That caused me to dump one application years ago when many hours of my work was destroyed in seconds.

I'm rating PDT a weak 4, but the others got only a 3, so I sent PDT's maker my money. I hope I will not be disappointed. I'm curious to see if they add a weight goal line to their weight chart. Almost every application has this. I'd also like total flexibility to trash several of the screens I don't use and never will.
