Everything you need
Sunwise gives you the tools to make smarter decisions about sun exposure — whether you're planning your day or checking in on the go.
UV Index Forecast
Get hourly and 7-day UV forecasts personalised to your exact location. Know when levels are rising, when to seek shade, and plan outdoor activities around the safest windows of the day.
Burn Time
Sunwise calculates your personalised burn time based on your skin type and the current UV index. Know exactly how long you can safely spend in the sun before protection is needed.
Apple Watch
A native watchOS companion that keeps UV data right on your wrist. Glanceable complications show your current UV index and remaining burn time, so you're never caught off guard.
Widgets & Intents
Home Screen and Lock Screen widgets keep your UV index front and centre without opening the app. App Intents bring Sunwise into Shortcuts and Siri for hands-free access anywhere.
