Instant Barcode Recognition for Allergen Safety

The core feature is a simple barcode scanner. Point the camera at any packaged food item, and Food Check cross-references the barcode against its database to determine if the product contains gluten, dairy, eggs, nuts, or other common allergens. The result is displayed as a clear pass or fail, saving minutes of label reading per item.

Business outcome: Reduces time spent on label analysis by up to 90% for users, enabling faster and safer shopping trips.

Expansive Global Product Database for Accurate Results

The app relies on a continuously updated database of food products from over 50 countries. This database is built from user contributions and verified sources, ensuring that the information on popular and regional items is current. The tool can identify products that are certified gluten-free or have specific allergen warnings.

Business outcome: Provides a high degree of accuracy for widely available products, building user trust and reducing false positives.

Customizable Allergen Profiles for Personalized Diets

Users can set up multiple allergen profiles, specifying which ingredients to avoid (e.g., gluten, dairy, soy, peanuts). The app then tailors its scan results to each profile. This is particularly useful for households with multiple dietary needs, allowing one device to serve the entire family.

Business outcome: Enables a single user to manage multiple, complex dietary restrictions without confusion, improving family safety.

Scan History and Dietary Logging for Tracking

Food Check maintains a history of all scanned products, allowing users to review their food choices over time. This log can be exported or shared with healthcare providers, such as dietitians, to track potential exposure to allergens and identify patterns in diet.

Business outcome: Offers a data trail that supports medical consultations and personal dietary management, adding a layer of accountability.

User-Contributed Product Verification Network

The app leverages a community-driven model where users can submit information about new products or flag inaccuracies. This crowdsourced approach helps the database grow rapidly and stay relevant, especially for local or niche brands that may not be in commercial databases.

Business outcome: Creates a self-improving ecosystem that increases the tool's value over time as more users contribute data.

Offline Mode for Shopping Without Connectivity

A premium feature allows users to download a portion of the product database for offline use. This is critical for users who shop in areas with poor cellular reception or who prefer to minimize data usage while in a store.

Business outcome: Ensures the tool remains functional in all shopping environments, removing connectivity as a barrier to use.

• Database breadthCovers over 1 million products from 50+ countries, with strong support for North American and European markets.
• User-friendly interfaceThe app is designed for quick, intuitive use with a clear pass/fail system that requires no training.
• Community-driven updatesThe database is constantly improved by user contributions, keeping it relevant for new and local products.

• Database gaps for niche productsLocal, artisanal, or very new products may not be in the database, requiring manual label reading.
• Reliance on user-submitted dataAccuracy depends on the community; a product's status can be incorrect if a user submits wrong information.
• Limited to packaged foodsThe app cannot scan fresh produce, restaurant meals, or bulk-bin items, which are common sources of allergens.
• Professional RealityFood Check is a powerful convenience tool but should never be the sole source of truth for severe allergies; always verify with the physical label and consult a medical professional.

Weekly grocery shopping for a celiac household

A parent managing a gluten-free home can scan every packaged item before adding it to the cart, ensuring no cross-contaminated products are purchased. This drastically reduces the risk of accidental gluten exposure for family members.

Traveling with food allergies

A traveler with a dairy allergy can use Food Check to scan local products in a foreign country, bypassing language barriers on ingredient labels and identifying safe snacks quickly.

Dietitian client consultations

A dietitian can use the scan history feature to review a client's recent food choices, identifying potential sources of inflammation or allergen exposure and providing targeted dietary advice.

Managing multiple allergies in one household

A family with one member allergic to nuts and another to gluten can set up separate profiles in the app, allowing each person to scan and get results specific to their needs from the same device.

Download the Food Check app from the iOS App Store and create a free account.

Set up your personal allergen profile(s) by selecting which ingredients to avoid (e.g., gluten, dairy, soy).

Open the scanner and point your camera at the barcode of any packaged food product.

Review the result (Safe / Caution / Unsafe) and, if needed, tap the product for more details on flagged ingredients.
