After about 5 years I may have a convert on my hands. My wife has a need to use Calorie Kings Diet Diary for managing my daughters diet. She was recently diagnosed as a diabetic. This was the perfect app to help her out in that dept. It allows you to count carbs and fat intake as well a lot of other things. I had my TX laying around the house for ebooks, remote control and music, now I have no better reason to use my TX. I not real happy about why she needs this, but I now it will help out in the long run. I am just glad I had this for her.
