What Matters in a Pollen App
Before comparing apps, it's worth establishing what actually matters for a pollen tracking app to be useful. Data quality (is the pollen data accurate for your specific location?), personalization (does the app give you generic information or information relevant to your allergens?), actionability (does it tell you what to do, or just what the number is?), and privacy (what happens to your health data?) are the four axes that differentiate useful apps from ones that look useful.

Anthos Allergy Intelligence — The Intelligent Pick
Anthos is the only allergy app using AI (Claude, by Anthropic) to generate a personalized daily reading — not a severity score, but a written interpretation of what today's conditions mean for your specific allergen profile. The app tracks 15 allergen species at species-level granularity (grains/m³, not index numbers), calculates your personal pollen threshold after 7 days of symptom logging, and combines pollen, AQI, and weather into the Anthos Score (1-100). It's ad-free and requires no account — all health data stays on-device.

My Pollen Forecast — The Best Free Option
The strongest of the free alternatives. Good pollen data, species breakdown, 5-day forecast. Does what it says. The trade-off: ad-supported interface with no personalization — everyone sees the same information.

The Bottom Line
If you want the most data possible for free, My Pollen Forecast is the pick. If you want an app that tells you what pollen conditions mean for your specific body — in plain language, every morning, without ads — Anthos is the clear choice and the 3-day trial costs you nothing to evaluate.
The rest of the category falls between these poles: pharmaceutical apps with commercial agendas, or general-purpose weather apps that treat pollen as a sidebar.
