Pollen

Which pollen is up today, and how much of it.

A single allergy number doesn't help when grass is fine and weeds aren't. Forecast Bar breaks today's count down by type, puts the worst one first, and names the trees behind it.

Free to download; live weather requires a subscription. On iPhone and iPad, every subscription includes a 7-day free trial for new subscribers; Mac plans do not. Mac and iOS plans are separate; Apple TV is included with Forecast Bar Gold on iOS.

Type by type

Find out which one is actually bothering you.

Pollen Count opens on the day's total, then splits it into tree, grass and weed, with mold when it's reported. Each type gets its own level and grain count, so a low total can't hide the one type that's running high. Tree pollen names the species behind it.

  • Total count in grains per cubic meter of air
  • A level and grain count for each type
  • Tree species, such as elm, ash or birch
  • The report's date and place, so you know how fresh it is

The worst type, right on the tile.

The Pollen Count tile gives you the level and the type driving it, so one glance tells you it's a weed day. Keep it among your main screen tiles, or put Pollen Count in a Home Screen or Lock Screen widget. Open the tile and the types are listed worst first.

  • Level and worst type on one tile
  • A choice in Home Screen and Lock Screen widgets
  • Main screen tile needs Gold, or Pro on the Mac

On your wrist

A pollen tile for Apple Watch.

The watch app's Pollen tile shows the level in a word over a five-color band, with the type driving it underneath. It's a reading rather than a screen of its own, so there's nothing to tap through. When there's no report, the tile steps aside instead of showing a dash.

An honest note: this is today's count, not a five-day pollen forecast.

Forecast Bar shows the latest report from a pollen counting station near you. It doesn't predict pollen for tomorrow or later in the week, so if you need next Tuesday's outlook, this isn't the app for that. There are no pollen alerts either.

The reports come from The Weather Company's stations, which cover the contiguous United States. Alaska, Hawaii, Puerto Rico and Canada aren't covered, and other locations show No Data. Stations report on weekdays, so weekends and holidays can come up empty.

Forecast Bar shows what was counted. It can't tell you how you'll feel, so keep your doctor's advice for your allergies.
