Open Allergy Map & Forum combines a global allergy map, official pollen data, user reports, and city forums. Unlike most allergy maps that only show official feeds, anyone can share the latest conditions in their city—or any place they know—so the picture stays closer to real time. Where the map can’t cover everything, the forums let people discuss country-specific meds and local conditions. The site also includes a built-in guide to the world’s major allergens.

Hi everyone — I’m the maker. I have severe allergic rhinitis. Before a trip to another city, I tried every mainstream site I could find to check what I’d actually be reacting to there — and none of them really solved it. Official pollen feeds often lag, don’t update well, and many places have little or no coverage. Travel (in-country and cross-border) is normal now, and allergies are getting worse for a lot of people. So I built Open Allergy Map & Forum: a global map with official data where it exists, plus live user reports for “how it feels right now,” city/country forums for local conditions and medications, and a built-in guide to major allergens. Would love your feedback — especially which cities or features you’d want next.
