## What is Pollens World?

Pollens World shows pollen risk anywhere in the world, with no Google, no account and no ads.

• 20 allergens tracked worldwide: 18 pollens (grass, birch, oak, olive, alder, hazel, ash, pine, poplar, mugwort, ragweed, pigweed, cypress, cecropia, urticaceae, casuarina, mulberry, plane) and 2 mould spores (Alternaria, Cladosporium), a common cause of summer rhinitis that feels exactly like hay fever.
• Clear risk gauge (0 to 100) and the day's dominant taxon.
• 3-day trend.
• Interactive world map: tap anywhere for the local risk.
• Allergy profile and personalised alerts based on your sensitivities.

Transparent reliability: in Europe, calibrated Copernicus CAMS data ("Calibrated"); elsewhere and for unmeasured taxa, a scientific weather-model estimate ("Estimated").

Privacy-first: your profile, favourites and settings stay on your device. No account, no tracking.


## Version history (last 5 releases)

### 1.8 — 2026-08-12

Important fix for threshold alerts: scheduled notifications were never delivered, because every app launch cleared them before reloading your settings. The Profile screen now shows the real state of the alert system: how many alerts are scheduled, a missing notification permission, or an unresolved location.

### 1.7 — 2026-08-09

An important mould fix.

Through the heatwave, Alternaria and Cladosporium levels stayed abnormally low. The cause was the 90-day rain total used to estimate damp organic matter: it actually read only the last 57 days, and counted the missing ones as days without rain. Cladosporium showed as "Moderate" where it should have read "High".

• The substrate is now read over a true 90-day window.
• Moulds finally appear in the 3-day trend and in threshold alerts, where they were scored zero every day.
• Corrected description: the app tracks 20 allergens, not 16.

### 1.6 — 2026-08-06

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.

### 1.4 — 2026-06-28

• Worldwide coverage now reaches the tropics: 5 new taxa — cecropia, urticaceae, casuarina, mulberry and plane. The equatorial belt is no longer blank.
• Southern-Hemisphere seasons fixed: flowering calendars now follow the local growing year instead of being six months off.
• Sharper weather model and better rain handling for more accurate risk estimates.

### 1.3 — 2026-06-04

• Pollen threshold alerts now fire reliably, even when the app is closed.
• Fixed the tab bar so it reaches the bottom edge of the screen.
• Stability improvements.
