A Suggestion:
A better scanner app for fitbit?
Using my Samsung Galexy Note 4 I was able to easily scan any Barcode easily using the My Fitness Pro App, as well as the fact that they have a large among of food in their database. Your aap makes things harder to scan and I am constantly sending in items for you to add to your darabase. Also, having a restaurant nutrients area in your database would be a great help.
