AllergyFlowCheck any food in seconds
Paste an ingredient list or scan a barcode or label. AllergyFlow shows which of your allergens the text names, and says so when it can’t tell.
Now on the App Store
Know what’s in your food.
AllergyFlow checks an ingredient list against your allergens in seconds, tracks your meals and reactions, and shows pollen forecasts for Europe. It reads the text you give it — it can’t confirm that a food is free of an allergen.

How it works
Everything you need, nothing you don’t.
Four tools that work together — check what you eat, track how you react, watch the pollen forecast, and ask for recipes that leave out your allergens.
Track every meal and reaction
Log what you eat and how you felt afterward. Patterns that take months to notice on your own start showing up in weeks.
See the pollen forecast for your area
Pollen forecasts for Europe, with your approximate location sent only to look them up, plus a look at whether pollen tracks with your rough days.
AI recipes that already know your allergens
Ask for a recipe that leaves out your allergens; the app checks the result against your list and flags anything it finds. A daily allowance is free, and AllergyFlow+ raises it.
Privacy by default
Built to keep your data close.
- Your diary and allergen list live on your iPhone and sync only through your own iCloud account.
- Pollen: an approximate location (about 10 km) goes to our server and on to Open-Meteo to fetch pollen, air quality and weather — and only when you open the pollen tab.
- Barcodes: only the barcode number is sent, to Open Food Facts, when you scan and when saved products are refreshed.
- AI recipes send your allergen list, meal type and cuisine to our server and OpenAI — only when you ask for a recipe, and never your name or email.
- No analytics SDKs, no ad identifiers, no tracking.
Read the full Privacy Policy for every detail.
Food diary
See the pattern, not just the reaction.
A single bad reaction rarely tells you much. A month of logged meals does. Your entries are stored on your iPhone and in your own iCloud account, building a personal record you can bring to your allergist — not a feed anyone else can see.
Questions
Frequently asked
Is my data private?
Your diary and allergen list are stored on your iPhone and sync only through your own iCloud. Some features send limited data to other services: an approximate location to our server and on to Open-Meteo for pollen, air quality and weather, a barcode number to Open Food Facts, and — only when you ask for a recipe — your allergens, meal type and cuisine to our server and OpenAI. We don’t use analytics SDKs or ad trackers. The Privacy Policy lists everything.
What's free and what costs money?
Checking food, your food diary and pollen forecasts are free for everyone. AllergyFlow+ ($49.99/year) raises the daily allowance of AI-generated recipes and supports independent development — that’s all it changes.
Which allergens does it detect?
AllergyFlow covers the major allergens — peanuts, tree nuts, milk, eggs, wheat & gluten, buckwheat, soy, fish, shellfish, sesame, celery, mustard, molluscs, lupin, and sulphites — matched against the ingredient text you provide.
Does it work outside the US?
Yes. AllergyFlow is available in 32 languages, with allergen matching tuned for each language rather than a direct translation of the English list. Pollen forecasts cover Europe only.
Can I cancel my subscription anytime?
Yes, anytime, directly through your Apple ID subscription settings — no emails, no retention flow.
