Built for the 13 million people in the UK who suffer from hay fever

I've had severe hay fever for as long as I can remember. Every June, without fail, my eyes would stream, my throat would itch, and my energy levels would completely crash.

Like most sufferers, I relied on weather apps to tell me what to expect. But the experience was always frustrating. I'd open a massive, bloated weather app, tap through three different menus, and finally find a tiny icon at the bottom of the screen that just said "High". High what? Tree pollen? Grass pollen? Was it going to be high all week?

I built Achoo because I wanted a tool that treated hay fever with the attention it deserves. A tool that didn't just throw a scary red "VERY HIGH" warning at me, but actually helped me understand my personal triggers and plan my week.

What we believe

Calm over alarm

Weather apps make pollen feel catastrophic. We show you the number, explain what it means for your specific sensitivities, and help you plan.

Private by design

Your symptoms and location are your business. We don't run ads, we don't use tracking pixels, and we don't sell data, ever.

Science, not pseudoscience

We source our pollen data from real environmental monitoring networks, and our AI insights are designed to cite their reasoning based on facts.
