It serves eight main functions:
1. Support multi-user to set up personal profile for calculating Body Mass Index (BMI) and Daily Energy Requirement.
2. Construct your personal database of your favourite prepackaged food.
3. Rank food in your personal database by contents of fat, sugars or sodium and show food which meets the conditions claiming low fat, low sugars or low sodium.
4. Exchange the information of food in your personal database with other users through Bluetooth.
5. Recognise daily upper limit and daily intake goal of different nutrients in scrolling widget.
6. With the amount of food consumed, estimate how much nutrients you will take.
7. Estimate your desirable nutrient intake as compared with the daily intake upper limit.
8. Keep track of nutrient intake and percentage of daily intake upper limit with reference to intake history records. (Retain maximum 30 records). User can also delete selected records.

Great Edmond ,

Wait for improvement

The concept is nice, but the application is lack of support! You know, most of people don't know the idea of the food calorie, there should be some sample of some favorable food list for choosing such as a bowl of rice.
