Very good app

The only negative thing I can say is that portions measurements does not support common American measurements like teaspoon, tablespoon, etc., and it needs a barcode scanning capability for food nutrient look-ups.
That said, it is the best app I have used for tracking all the little things that diabetics need to keep track of. Of all the trackers I have tried this one is the best and well worth the small fee. Once they update the barcode thing, I will give them 5 stars.
