Haelo is live

Live your season.
Help end it for good.

Not another pollen counter. An honest 5-day forecast for your area — and a season that learns you behind it.

What it does

Three layers, one pocket.

Forecast

Five days, per species — birch, alder, grass, mugwort. Hourly for tomorrow. Source-transparent, district-rated, no 14-day theatre.

Understand

Apple Health signals, daily logs and the personal pollen threshold the app learns from your season.

Act

A 30-rule engine turns live research into actions you can take now — medication timing, pre-season prep, rain windows.
