Customer Allergy Log.
An app idea for restaurants.

A phone number lookup that shows a regular customer's allergies and preferences before staff take the order.

Gap foundResearched 23 September 2026 for restaurants

What the search found

Who pays
Restaurant owner or manager at a sit down restaurant with regulars
The problem
Servers say guests expect the restaurant to already know their allergies, and regulars with long allergy lists are hard to serve safely. One wrong dish is a health risk and a legal risk.
The gap
Existing allergen platforms manage the menu side, mapping ingredients and recipes. None of the results is a lightweight guest side record keyed to a phone number that a small restaurant can check in seconds when a regular calls.
Already out there
  • CertiStar certistar.com

    Checks recipes and ingredients against allergies and builds guest profiles. It is a full platform aimed at larger operations, not a quick lookup for a small restaurant.

  • AllergyMenu allergymenu.app

    Customer facing allergen display plus back of house allergen data management. It covers dishes, not the individual regular's history.

  • AllergenOnline allergenonline.org

    A scientific allergen protein database. It is a reference tool, not an operational guest record.

People asking for it
The big assumption
Staff will actually look up a customer before taking an order during a busy service.
Test it this week
Run a paper allergy card file for ten regulars at one restaurant for two weeks and count how often staff check it before taking an order.
