Pollen & Allergy Forecast

Today's pollen index, the worst allergen, and the best low-pollen window to head outside — plus a symptom diary that learns your triggers.

Stop letting hay fever ambush you. Pollen & Allergy Forecast shows today's pollen index at a glance, breaks it down by the allergens that actually trigger you, and tells you when it's safe to go outside — so you can medicate early, close the windows in time, and pick the right moment for a walk.

A glance at the home screen tells you everything: the overall pollen index, the main allergen in the air right now, and a plain-language read on how likely you are to feel symptoms today.

WHAT YOU GET

• Today's pollen index & symptom risk — a clear index with an honest, readable forecast of how bad symptoms are likely to be, from "low, most people feel fine" to "very high, start medication early." • Pollen by type — separate levels for TREE (alder, birch, olive), GRASS, and WEED (mugwort, ragweed) pollen, in grains/m³, so you know whether it's the birch or the grass that's getting you. • Good-time-to-go-out window — finds the lowest-pollen window in the next 24 hours so you can plan a run, a walk or hanging washing when the air is clearest. • 5-day pollen outlook — the daily peak index and dominant allergen for the next five days, with the worst day ahead flagged. • Symptom diary & correlation — log how bad your symptoms feel each day (0–4). Over time the app shows how closely your symptoms track the pollen count and which allergens look like your strongest triggers.

WHO IT'S FOR

Hay fever and seasonal allergy sufferers, parents tracking a child's allergies, anyone with pollen-sensitive asthma, runners and gardeners who want to time outdoor time, and people trying to pin down exactly which pollen sets them off.

HOW IT WORKS

Pollen forecasts come from the Open-Meteo air-quality model for your location. Enable location for your local forecast, or browse sample data offline. Your symptom diary stays on your device.

A NOTE ON ACCURACY

Pollen values are forecasts and estimates in grains/m³, not a measurement at your nose. They vary with wind, rain and the plants near you. The symptom diary is a personal tracker, not medical advice — see a clinician for persistent symptoms.
