Sunwise: UV Index & Sunburn

Sunwise is your personal sun-safety companion. It turns the daily UV forecast into clear, tailored guidance so you know exactly when to seek shade, reapply sunscreen, or head outside with confidence. Built on Apple WeatherKit and designed for iPhone, iPad, and Apple Watch.

HOURLY AND DAILY UV FORECASTS
See the UV index hour by hour and get a multi-day outlook for any location. A detailed line chart shows how exposure rises and falls throughout the day, so you can plan around the hours that matter.

PERSONALIZED BURN TIME
Add your skin tone and how easily you burn. Sunwise estimates how long you can safely stay outside at the current UV level, helping you decide when it is time to cool down, cover up, or reapply sunscreen.

SMART FORECAST SUMMARY
Get a plain-English summary of your day’s sun exposure generated on-device with Apple Intelligence. Private, fast, and tailored to your skin profile.

SUN EVENTS
One glance for sunrise, sunset, solar noon, peak UV time, and today’s safe hours.

MULTIPLE LOCATIONS
Track home, work, the cottage, and your next holiday. Sunwise remembers your places and keeps each forecast updated.

HOME SCREEN AND LOCK SCREEN WIDGETS
Pin widgets for Current UV, Burn Time, Hourly UV, and the Daily Outlook anywhere on iOS. Background refresh helps keep your information current all day.

APPLE WATCH APP AND COMPLICATIONS
Check your forecast on your wrist, with complications that show UV index and burn time directly on your watch face.

SIRI AND SHORTCUTS
Ask Siri “What’s the UV?”, “When’s peak UV today?”, or “Do I need sunscreen?” for an instant answer. Create routines with App Intents.

iPad SPLIT VIEW
View multiple locations side by side with a full-screen forecast, so planning is quick and effortless.
