Do you need sunscreen today, and until when? Kremik, the UV index app, answers at a glance, so you don't have to dig through a weather app for UV numbers.

FREE
• A clear answer: “Sunscreen needed today: 10:40 AM – 4:10 PM” or “No sunscreen needed”, based on the WHO threshold of UV 3.
• The UV index (also called the UV rating or UV level) right now and hour by hour, with cloud cover taken into account (Copernicus CAMS forecast).
• A UV index widget for your home screen in four sizes, light and dark.
• A morning reminder, only on days when you actually need sunscreen. In winter, the app stays quiet.
• Forecast for today, tomorrow and the day after, near you or for any city in the world.
• No ads, no account, no tracking.

HOW IT WORKS
Kremik uses the Copernicus (CAMS) UV forecast with clouds, rounded up for safety, and the protection threshold set by the World Health Organization. Unlike a weather app, it doesn't stop at a number: it tells you whether you need sunscreen and for which hours.

PRIVACY
Your location is approximate, used only while the app is open and rounded to about 11 km.

Kremik does not provide medical advice.
