Recently, one of my friends told me about the advantages of a food journal, that she could not only check for the calories and nutrients in the food she eats, but also review her diet and daily activities in it. I found it quite interesting, and I downloaded from mynetdiary free which is apparently a food log from mynetdiary. On my Android phone, however, this food log doesnât show the details of BMI, pulse, blood pressure, BMR, bone weight etc. I want to now know how much am I supposed to pay for upgrading to a detailed version of food log on my Android phone? Can somebody please advice?
