UV Index - Today

Check the UV before you head out. See live UV, your personal burn time, and the best windows to tan or cover up, all tuned to your skin type.

UV Index: Know Your Sun

Know exactly when to catch the sun, and when to cover up. UV Index shows the live UV index for your precise location, your personal time to burn, and the safest windows to be outside, all built around your skin type.

Whether you are chasing a glow or protecting your skin, UV Index turns the day's UV into clear, personal guidance you can act on at a glance.

WHAT YOU GET

• Live UV index, hour by hour, for anywhere in the world • Your personal time to burn, based on your skin type and the SPF you are wearing • Best tan windows: the parts of the day that are strong enough to tan but easier on your skin • A sun session timer that counts your time outside and tells you when to reapply or head in • Home Screen and Lock Screen widgets that show your current UV at a glance • Apple Health sync for time in daylight and UV exposure • Smart alerts the moment UV climbs to your level, plus a peak of the day heads up • A clear outlook for the week ahead so you can plan around the sun • Search any city in the world, in your own language

PERSONAL TO YOU

Set your skin type and the SPF you usually wear, and every estimate adjusts to you: your time to burn, your safe window before you should reapply or find shade, and the alerts you receive. The more honest you are about your skin, the more useful the guidance.

A SUN SESSION, NOT A GUESS

Tap start when you step outside and UV Index counts your minutes in the sun against your personal burn time. It coaches you in plain language: you are in the safe zone, time to reapply, or time to head in. End the session and it logs your time in daylight and UV exposure to Apple Health.

HONEST ABOUT THE SUN

UV Index is built to help you enjoy the sun more safely, not to push you into it. The app is clear that no amount of UV tanning is risk free, and it is full of plain language sun safety guidance so you always know what the numbers mean.

DATA YOU CAN TRUST

UV data comes from Open-Meteo and already accounts for cloud cover, with Apple Weather as an automatic backup if Open-Meteo is unavailable. Your health data never leaves your device, and your location is used only to fetch the forecast. No accounts, no ads, no tracking.

IMPORTANT

UV Index provides estimates and general sun safety guidance, not medical advice. No amount of UV tanning is risk free. If you have fair skin, many moles, or a history of skin cancer, take extra care and speak with a professional.
