App that protects you from food allergies/tolerances

Description

How great would it be to shop in a supermarket or eat in a restaurant not worrying about what it contains (gluten, nuts etc) when your data has already synced up and has blacklisted what you cannot buy or order.

Target Audience

Everyone who has a food intolerance or allergy, it also includes those who are on strict diets.

How do people solve this problem now?

Currently, people carry medicine such as antihistamines or epi-pens (adrenaline) . But food allergies such as nuts are not always visible, it may be in the form of a powder or oil in foods and hard to detect. The app will pull health data and sync with supermarket label ingredients or restaurant menu recipes to rule out and black list anything that the you cannot eat/order.
