Redesigned Forecast
Clearer cards for today and tomorrow, with color-coded hourly bars, the weather for each hour, and when you'll need sun protection. The coming days are one tap away.
Redesigned Settings
Settings have a new card design that's easier to scan and quicker to find your way around.
Two Columns on Bigger Screens

Review momentum (0-100) blends how fast the app collects ratings compared with other apps in its category (60%), whether that pace is speeding up (25%) and what recent raters give it (15%; recent stars well below lifetime pull it down). Ratings counts are read daily. A jump usually means a launch, a feature, ads or a new review prompt.
About UV Index Widget - Worldwide
UV Index Widget - Worldwide brings one of the most useful pieces of weather data, the UV Index, front and center. Use this app to track your UV exposure, help plan your day outside, and avoid burning. Perfect for planning your tanning routine.
UV Index Widget - Worldwide is a convenient app that lets you monitor the Sun’s radiation levels anywhere on Earth. It shows the current UV Index, today’s peak forecast, and a 7-day UV forecast. You can add the UV Index to your Home Screen via widgets, receive alerts when UV Index reaches specific levels, and automatically log the data to your Apple Health app.
The app instantly displays your current UV Index (UVI) in an easy-to-understand format. Just tap and hold to view today's highest UVI reading. You can also check the sunrise and sunset times, along with the moment when the UV Index peaks.
7-day hour-by-hour forecast:
The Forecast tab provides an hour-by-hour UVI prediction for the next 7 days.
My Skin:
In the My Skin section, select your skin type for tailored safety tips and recommendations. You can also monitor your sun exposure and receive alerts when there’s a high risk of sunburn. Additionally, the app tracks your Vitamin D production from sunlight and automatically syncs the data to your Apple Health app.
Places:
In the Places tab, you can select any location around the world to see its current UV radiation and a 7-day forecast. It's a great tool for checking the UV levels at your travel destination before you head out.
Widget:
The app offers a variety of Home Screen widgets and Lock Screen Widgets, designed for both your iPhone and Apple Watch. Choose from multiple options to customize your experience on the Home Screen, Today view and Apple Watch.
Notifications:
The app alerts you when the UV Index exceeds your specified threshold, sending a notification whenever your area's UV levels surpass that mark. It also warns you when you're at high risk of sunburn and reminds you to reapply sunscreen.
Apple Health app:
The app automatically logs your location's hourly UV Index and the vitamin D generated from sun exposure into the Apple Health app. Open Apple Health to review your UV exposure history and vitamin D data.
Apple Watch:
Monitor the UV Index directly from your watch. Tap and hold to view today's peak UVI, just like in the iOS app. The watch app also features a My Skin section and a 7-day hourly forecast. Additionally, you can always check the UVI right on your favorite watch face using the included UVI complications.
The app will work anywhere in the world, and is a perfect companion whether you are at home or travelling.
