For anyone who needs to know before they arrive

Don't lose the trip to something you could have checked.

Pollen by species, air, humidity, UV, altitude, water, for the exact place, before you book it.

What you get:

The holiday happens. For most people a bad week somewhere is a bad week. For you it's an inhaler, a fortnight of antihistamines, or going home early.

You stop guessing from a forecast. "High pollen" is useless if you react to one species. You get the six separately, and the weeks each one runs.

You see the two months that matter. A city's annual air average hides them. The seasonal shape doesn't.

You can plan a long stay properly. Somewhere you'll be for three months is a different question from somewhere you'll be for three days, and it deserves the numbers.

You walk into the doctor's office with data. We won't tell you a place is good for you, we're not doctors and we don't know your history. We hand you the measured values, named to their sources, so that conversation starts from evidence rather than a brochure.

Every metric is explained, what it measures, what it doesn't, and where coverage thins.

Then compare the alternatives on a 28-Day Pass. Most people are choosing between three or four places; the pass covers the whole decision.

Click a cell and it shows you why it scored what it scored.

The workings stay on the page: value, source, standard. If a place looks too good, you can see exactly what made it look that way.

Free reads one cell. The pass reads all of them at once.

Run as many single cells as you like. What free cannot do is put them side by side, rank them, or hand you the table.
