Jacket?

Do you need one? Yes or no.

You open it, and it says one word. No dashboards, no radar map, no fourteen-day outlook you were never going to read — just the answer, and a single line telling you why.

How it decides

It looks at the next six hours where you actually are, not the city average, and checks four things in order:

• Rain now, or likely soon, while it is still cool
• The coldest it is going to feel in that window
• How cold it feels right now
• Wind over 20 mph with a chill on it

The first one that trips gets you a jacket, and the reason line says which.

Runs hot? Runs cold?

One slider, eight degrees either way. The app shows the cutoff it landed on — “You run cold — jacket below 68°” — and re-answers as soon as you let go.

Requirements

iPhone and iPad, iOS 17 or later.
