SUNZA
A weather-aware packing app for iOS and Android

Pack for the weather you'll actually face — with clothes you already own.

Sunza checks the forecast for your destination and builds a packing list that shows you why every item's on it.

Your wardrobe · on your device

It packs the clothes you already own.

Snap your clothes once and Sunza sorts them into a wardrobe. Then it suggests your own garments for the trip — each with its weather reason, like the rest of the list. So the list says your grey fleece, not “a warm layer.”

Everything stays on this device. Photos are never uploaded — only a downscaled copy of the ones you pick is kept.

How it works
1
Tell it where and when.

A destination and your date range. Nothing else.

2
It checks one forecast.

For your exact window at your exact place.

3
You get a list that explains itself.

Every line says why it's there. It works offline, too — so it's with you at the airport.
