AllerGen - Allergy Tracker

Feel more organised around food allergies with AllerGen — a practical UK-focused companion for allergy profiles, ingredient-label checks, food and reaction records, and medicine reminders.

BUILD YOUR ALLERGY PROFILE

Choose from 30 common allergens, add custom allergens and record severity levels. Your selected profile is used when you check ingredient text.

CHECK FOOD LABELS WITH ALLERGEN PLUS

The optional lifetime purchase lets you photograph an ingredient label, choose an image from your device or type the ingredients yourself. AllerGen compares recognised text with your allergy profile and highlights matching terms and precautionary wording for you to review.

Text recognition can miss or misread ingredients. Always read the original packaging and “may contain” statements yourself. No match does not guarantee that a product is safe or free from cross-contact.

KEEP USEFUL FOOD AND REACTION RECORDS

Record meals and whether they felt safe. Log possible triggers, symptoms, severity and notes after a reaction. Review your history before speaking with your GP or allergy specialist. These records cannot identify or diagnose the cause of a reaction.

PLAN MEDICINE REMINDERS

Create a schedule using the medicine name, number of whole tablets per dose, prescribed interval, and first reminder date and time. Confirm doses as taken or missed, review adherence history and remove every scheduled record for a medicine when it is no longer needed.

Android notification permission and battery settings can affect delivery. Follow the label and your prescriber’s instructions. AllerGen does not recommend doses or advise how to make up missed doses, and should not be your only reminder for time-critical medicine.

PRACTICAL EVERYDAY SUPPORT

• Browse allergy-aware ingredient-swap ideas.
• Read clear food-allergy guides with NHS and Food Standards Agency links.
• Review descriptive patterns from saved food and reaction entries.
• Keep key information together for shopping, meal planning and appointments.

OPTIONAL ALLERGEN PLUS — ONE PAYMENT, LIFETIME ACCESS

A confirmed Google Play purchase unlocks:

• Camera, photo and typed ingredient checks.
• Household profiles for partners, children and carers, with separate allergy profiles and journals.
• Saved products, favourites and previous ingredient checks.
• Personal meal plans and allergy-aware shopping lists you create.
• Longer-term journal summaries covering 30, 90 and 365 days.
• PDF health reports for appointments.
• Medicine adherence history, missed-dose tracking and CSV exports.

Household profiles are stored locally. Saved products, plans, shopping lists and medicine records are shared on the device. Summaries describe your entries; they do not diagnose allergies or prove cause and effect.

Premium access requires a confirmed Google Play purchase. The app displays the current local price before purchase. Restore access with the same Google Play account.

PRIVACY AND CONTROL

Your health and journal records are stored locally on your device. You decide what to save, delete and export. Purchase services process information needed to provide paid access. See the privacy policy for full details.

IMPORTANT SAFETY INFORMATION

AllerGen is an organisation and awareness tool. It is not a medical device, diagnostic service or substitute for professional medical advice, and it cannot guarantee that food is safe. Speak with your GP or allergy specialist for personalised advice. In an emergency, call 999.
