The problem

400 million people lose weeks of their lives every year to 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.

The Haelo system

Finally, a hayfever companion
that knows you.

Three interlocking layers. Each useful alone — together, something that has never existed before.

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

Daily recommendations backed by live research. The engine continuously synthesises new science and translates it into actions you can take right now — before symptoms arrive.

The research engine

Science that actually
reaches you.

◎

Academic queries

AI-driven search across PubMed, Cochrane and specialist allergy databases.

◈

Evidence grading

Studies summarised and graded for quality. Weak evidence never reaches you as a recommendation.

◉

Translation

Research converted to practical daily actions — supplement timing, food choices, route adjustments.

◌

Personalisation

Recommendations filtered through your profile, history and current exposure level.
