Personal hayfever intelligence
Live your season.
Help end it for good.
Not another pollen counter. Haelo reads your air, learns your patterns, and tells you what to do about it today.
The problem
400 million people lose weeks of their lives every year — to fog, exhaustion, cancelled plans and quiet misery — from a condition that existing tools barely address.
Generic forecasts
Regional pollen counts tell you what's happening in your county — not your street, your commute or your park. They're averages over large areas that mean nothing to your specific exposure.
Reactive management
Antihistamines taken after symptoms arrive. Steroid injections each spring. A cycle of reaction, not prevention. The tools most people have were designed to manage symptoms, not eliminate them.
Lost weeks
Brain fog, poor sleep, reduced productivity, cancelled plans. For moderate-to-severe sufferers, hayfever season means weeks of diminished quality of life — and that is considered normal.
We believe
Hayfever is not a minor inconvenience. It's weeks of fog, missed mornings and lost plans — and the tools most people have were built to cope with it, not to end it. Your season is yours. It's time to take it back.
The Haelo system
A hayfever companion
that knows you.
Your triggers, your patterns, your season — and what to do about it today. Three layers, working together, so you stop guessing and start knowing.
Sense
Your real air
The Haelo Clip measures your actual pollen exposure — not a regional average. Your route, your breathing zone, your environment. Streamed into your personal history continuously.
Understand
Your patterns
Your symptoms against your behaviours. What you ate. Where you went. What helped. Haelo surfaces connections that explain your good days and your bad ones.
Act
Today's advice
When to take your antihistamine. Which route runs cleaner today. When a rain window will clear the air. Specific, personal actions — synthesised from live research, delivered before symptoms arrive.
Who it's for
For people ready to stop coping.
“I want to understand what's actually working.”
— The curious
“I've tried everything. Nothing sticks.”
— The pragmatist
“Show me the evidence before I trust it.”
— The informed
