How can we help?

When you first open AllerGuide, you'll be guided through a setup flow where you can select all of your allergens from a list of 25+. You can update these at any time from the Profile tab — just tap any allergen to toggle it on or off.

Yes — you can browse dishes and explore the app as a guest. Creating an account (free) lets you save your allergen profile so it persists across devices and app reinstalls, and unlocks the AI chat and phrase translation features.

On the sign-up or sign-in screen, tap "Continue with Apple." You'll be prompted by iOS to authenticate with Face ID or Touch ID. If you choose to hide your email, Apple will provide a private relay address — AllerGuide works fine with either.

AllerGuide's dish data is based on typical, traditional recipes. Actual ingredients vary by restaurant, chef, and region — so while we flag known allergens in standard preparations, you should always verify with restaurant staff before eating. AllerGuide is an informational tool, not a medical device.

AllerGuide covers 25+ allergens including peanuts, tree nuts, dairy, eggs, gluten, sesame, crustaceans, molluscs, fish, soybeans, mustard, celery, lupin, sulfites, pork, and more — including less common ones like beehive products, buckwheat, and specific fruits.

Because recipes vary. A dish that's typically peanut-free may be prepared with peanut oil at a specific restaurant. AllerGuide gives you the best available general information, but cross-contamination and recipe variations are real — always confirm with the kitchen.

Pro unlocks unlimited AI chat conversations and the ability to save allergy phrase cards for offline use. The free plan includes a limited number of AI messages per month and access to the full dish database.
