We also want the app to feel very reliable, and it should never feel unresponsive, slow, of disconnected.
People expect value added deciphering, in context, and they need to feel the advice is personalized for them.

Scan should be continuous, and instant (with a local copy of the essential information available offline), in all directions, and work in bad conditions (low light, bad camera, 90 angle, broken main camera)
The result should display what it currently does on Android: Nutri-Score, NOVA group, CO2, # of additives (along with a first time explanation to scroll up the scan card for more details and explanations), diets if not disabled, and allergen warnings if enabled
Scan requests should be specified as such to the server, with an HTTP header. They should use the fields= API to minimize payload.
