Most weather apps answer the wrong question.

They tell you it's 12°C outside. That's accurate. But whether 12°C means you need a coat depends entirely on who you are — and weather apps don't know you.

That friction is what Samukunai ('Are You Cold?') is built around.

How it works

The mechanic is minimal: tap warm or cold after you check the morning forecast. That's the only input you give the app.
