How it works

1. 1

   Scan or search

   Open the app with no account. Scan a barcode or type a name. The catalogue is checked first. A barcode it does not know stays unknown.

2. 2

   Read the match

   The ring shows 0 to 100 with a word and an icon. Every point that moved the score is listed. Set preferences if you want them. Skip leaves them unset.

3. 3

   Swap, compare, or list it

   A closer match in the same category is offered when one scores at least 10 points higher. Add the food to a list only if you want it there.
