I have the Charge 2 and the barcode scanner doesn't work for me. The app is presumably the same no matter which Fitbit you have though so shouldn't make a difference.
It annoys me that whenever I try to use it, it offers the suggestion of me uploading photos to add items to the barcode list. It doesn't work in the UK, it knows I'm in the UK so why does it keep asking for help with photos? You can't go any further, it doesn't tell you why, it's only through doing a Google search that I found out we can't use it in the UK.
It also annoys me that when adding custom foods on the app, although there is a screen for adding characters (the decimal point), it will not actually allow you to use it. That's madness. Not a problem if I do it on the website just not possible to add new foods on the fly, you know, when you're actually eating them and have the wrapper to hand.
