Had to pay an extra dollar to use bar code scan after I bought pro version which I was not aware of...must of missed that fine print. Then Not one thing I tried to scan was in system and I tried tons of items. Entering food on your own is complicated and time consuming. Had to reenter some things many times because of the way you enter servings. Like that it tracks calories carbs fat and protein: but not worth the trouble.
