As a nasal allergy sufferer myself, I built Hayfever to help better understand what triggers my allergy symptoms and what I might be able to do to avoid them.
Hayfever lets you self report allergy symptoms when and where you are having them. The app will store the best available information about the allergens present, including pollens and air quality measurements.
Over time you can build a profile of what triggers your worst attacks and perhaps learn how to avoid it.
