August 6, 2026
An important accuracy fix, plus two new allergens. Risk is now computed from the day's peak rather than a single moment, and the scale has been realigned with the clinical thresholds used across Europe. Genuinely heavy days are reported at their true level again and threshold alerts fire as expected. The app now also tracks two moulds, Alternaria and Cladosporium, the main late-summer aeroallergens. Their spores cause symptoms indistinguishable from hay fever, and they peak in hot dry weather, exactly when pollen counts fall.
