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.

UV Index Widget - Worldwide is a handy little app to check the current radiation level from the Sun (the UV Index), the highest UV Index forecast for today, and the forecasted UV Index for the next 7 days, anywhere on Earth. You can also add the UV Index to your Home Screen using the accompanying widgets, set notifications for when the UV Radiation exceeds certain levels, and automatically add the UV levels to your Apple Health app.

The app will instantly show the current UV Index (UVI) at your location in an intuitive way. Tap and hold to see the peak UV Index for today. You can also see when the Sun rises and sets, and at what time the UV Index is at its highest level.

7-day hour-by-hour forecast:
The Forecast tab will show hour-by-hour UVI forecast for the next 7 days.

My Skin:
In the My Skin section, choose your skin type to get personalized safety information and recommendations. You can also track your sun exposure, which will notify you when the risk of getting a sunburn is high. The app can also track your Vitamin D generation from sun exposure. Vitamin D generated is automatically added to the Apple Health app.

In the Places tab you can select any place on Earth to view the current UV radiation and 7-day forecast for that location. Handy when you are about to travel somewhere and want to get a heads up on the UV radiation level where you are going.

iOS 14 home screen widgets are now supported. Choose between 7 different home screen widgets, and add them to either you Home Screen or the Today screen.

The app can notify you when the UV Index goes above a certain level. Set the desired UV Index you wish to be notified about, and you will receive a notification if the UV Index at your location goes over this treshold. The app can also notify you when you are at high risk of a sunburn, and remind you to reapply your sunscreen.

Apple Health app:
The app will automatically store the hourly UV Index for your location in the Apple Health app. Open the Apple Health app to view your UV Exposure history.

Apple Watch:
You can now check the UV Index on your watch. Tap and hold to view todays peak UVI, just as in the iOS app. The watch app also contains a My Skin section and 4 day hourly forecast. In addition you can check the UVI any time right on your favourite 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.

Simple, beautiful app and a friendly developer

I love data, and I sunburn in 15 minutes, so it's no surprise that I've tried just about every UV index app in the app store. I've been a little unsatisfied with all of them until now; either they don't have features I want, or the API they're using stops working and the dev never fixes the app. This app is thoughtfully designed and a pleasure to use. After emailing the dev, Bjørn, to ask about adding a feature, I feel even happier about supporting his work. He was very friendly and replied within a day to let me know the feature already existed in the app and how to use it.

For those curious: I asked about a feature to notify me when the UV index drops below a certain level, and Bjørn told me that whatever threshold I set for a "too high" notification, the app will tell me when the UVI goes above *or* below that. I just got a notification that the UVI dropped below 4, which means it's almost time for my walk, no sunscreen needed for me. :)

If you're looking for cleanly presented, detailed data on the forecasted UV index and time to burn for your location, skin type, environment (pavement, snow, etc.), time of day, cloud cover, and more, this is your app. I paid for the pro features and would do it again in a heartbeat.

Strait to the point

Lots of apps have the UV index buried in the app. Dark sky has this too, but hunting for it with 15 taps is a pain. This app brings one of the most useful pieces of weather data front and center so I can plan my day and track my exposure. In the summer this app is a lifeline to help me avoid burning, and help me to know that even though the sun may be “hot” it may not be in the UV exposure that is harmful. In the winter and shoulder months, this app helps me to plan the most pleasant times to be outside, as the sunshine is often more useful than raw temperature.

Fully supports widgets, Apple Watch, AW complications and great info. Thank you!

Almost perfect

I’m very pale and burn easily. I work outside in the ecology field. 99% or my work day is spent outside and I need proper sun protection. This app is amazing for people like me who need to respect the sun. My only complaint is the function where the app warns you once a specified UV rating has been reached. I currently set mine to 3. Every time I get the notification alert that it’s UV 3 I open the app to find out that it’s well above UV 3. This isn’t a big deal to most people but for a lot of us this can be a matter of getting burnt or not. Still though. Very happy customer. App looks and feels good to use. The amount of times I’ve been sun burnt has gone down a lot since finding this app. However i fell that success rate would be higher if the alert notification mentioned earlier was more accurate.
