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, and cook without worry.
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.
Know today's pollen before you go outside
Daily pollen forecasts for the allergens that affect you, plus a look at whether pollen tracks with your rough days.
AI recipes that already know your allergens
Every suggestion is checked against your allergen list before it reaches you. 10 free recipes a day, unlimited with AllergyFlow+.
Privacy by default
Your data doesn’t leave your phone.
- Your food diary and allergen list are stored only on your iPhone, using Apple’s on-device SwiftData framework.
- Location is used only to fetch local pollen levels — never stored on our servers, never shared beyond that one request.
- No analytics SDKs, no ad identifiers, no tracking — of any kind, ever.
- AI Recipes send only your allergen list and meal type — never your name or identity — and nothing is retained afterward.
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. Every entry stays on your phone, building a private record you can bring to your allergist — not a feed anyone else can see.
Questions
Frequently asked
Is my data private?
Your food diary and allergen list are stored only on your iPhone using Apple’s on-device SwiftData framework. We don’t use analytics SDKs or ad trackers. Full details are in the Privacy Policy.
What's free and what costs money?
Checking food, your food diary, and pollen alerts are free for everyone, forever. AllergyFlow+ ($4.99/week or $49.99/year) removes the daily cap on AI-generated recipes — that’s the only thing 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.
Can I cancel my subscription anytime?
Yes, anytime, directly through your Apple ID subscription settings — no emails, no retention flow.
