Allergo is a mobile app designed for travelers with food allergies, coeliac disease, or medicine allergies. It generates translated allergy cards that restaurant staff can easily understand, eliminating the language barrier that often leads to dangerous miscommunication. Built with input from NHS healthcare professionals, Allergo covers 27 allergens across 36 languages, each translation localised per country rather than word-for-word. Its core value is giving users the freedom to eat safely anywhere in the world, turning a stressful dining experience into a confident one. The app is especially valuable for those who have spent years navigating allergies, offering a reliable tool that reduces anxiety and ensures clear communication.
The concrete problem Allergo solves is the health risk posed by language barriers when traveling with allergies. One in ten people have a food allergy, yet most travel without a reliable way to communicate it. Menus are unreadable, staff may not understand, and the constant worry of an allergic reaction follows every meal abroad. This is not just inconvenient—it can be life-threatening. For parents of allergic children, the stress multiplies as they must translate and double-check every dish. Allergo removes this burden by providing a clear, accurate card that explains exactly what the user cannot eat, in the waiter's native language. It turns a potentially dangerous situation into a safe, straightforward interaction.
The first major feature group includes instant allergy cards and the Apple Wallet pass. Users pick their allergens from 27 options covering food, cosmetics, and medicine, then select their destination country. Allergo generates a restaurant-ready card in seconds, localised with accurate terms for that region. This card can be added to Apple Wallet for instant access without opening the app. Tapping the card reveals a QR code that diners can show directly to a waiter or chef, ensuring no verbal miscommunication. The benefit is speed and simplicity: no fumbling with translation apps or paper notes. The card is always available, even without internet, and includes critical warnings like "may cause severe allergic reaction."
The second major feature group is the SOS Emergency and Response Helpers. With one tap, the SOS feature surfaces critical information: allergy details, emergency phrases, and local emergency numbers for wherever the user is. This is invaluable during an allergic reaction when every second counts. Additionally, Response Helpers provide follow-up phrases to confirm if a dish is safe, such as "Does this contain peanuts?" without needing a separate translation app. These features work together to cover the entire dining experience, from ordering to handling emergencies. They give users the confidence to navigate restaurants independently, reducing reliance on friends or family to translate.

The third feature group includes fully offline access and localisation per country. All cards and phrases remain accessible even without a signal, crucial for remote areas or basement restaurants. Translations are not generic but tailored to each country, capturing local terms and dishes that might hide allergens. For example, a card in France uses French culinary terminology familiar to local chefs. Allergo covers all 14 major EU and 9 US regulated allergens, plus additional common triggers, totaling 27. The app is built with input from NHS professionals, adding medical credibility. This ensures that the information is not only accurate but also conforms to regional regulations and cultural dining norms.
Allergo's approach is straightforward and user-friendly. The workflow starts by selecting allergens from a comprehensive list of 27 options, including food, gluten, dairy, peanuts, tree nuts, eggs, fish, and medicine allergies. Next, users choose their destination from 36 languages, each localised per country. The app then generates a clear, restaurant-ready card that can be saved to the app or directly to Apple Wallet. The cards are currently generated using leading AI models, with select languages reviewed by native speakers. Allergo aims for full professional translation across all languages for complete peace of mind. The entire process takes under a minute, making it practical for pre-trip preparation or on-the-go use.
Concrete use cases abound in user reviews. A parent of a child with severe allergies finds the app "so helpful with the stress of travelling with a young family." A gluten-intolerant traveler in Southeast Asia previously struggled with Google Translate but now uses Allergo cards to explain their needs easily. Another user with peanut allergies says the app makes traveling "so much smoother" and gives "real peace of mind." Even an allergist praised it as "completely awe-stricken" at the quality. These scenarios show how Allergo transforms a risky, anxiety-filled experience into a safe, confident one. Users no longer need to rely on makeshift translations or hope for the best; they have a professional tool that works every time.
Allergo targets anyone with food allergies, coeliac disease, or medicine allergies, especially those who travel frequently. It is also invaluable for parents of allergic children and professionals like allergists who recommend solutions. The app runs on iOS with Apple Wallet integration; an Android waitlist is open. Pricing is simple: free to download with one free card, then a monthly plan at £3.99 (ideal for single trips) or an annual plan at £19.99 (best value for frequent travelers, saving over 75%). Subscriptions fund new allergen coverage and professional translations. Ultimately, Allergo gives users the freedom to eat anywhere safely, removing language as a barrier to health and enjoyment.
People with food allergies, coeliac disease, or medicine allergies who travel abroad and dine out; parents of children with severe allergies; health professionals such as allergists seeking a trustworthy patient tool; families concerned about cross-cultural communication of dietary restrictions; and any individual with anaphylactic risks requiring precise, locally accurate translation of their allergens.
