The UV Index app that has it all!

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 Today Screen using the accompanying widget, 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.

In the Map tab you can select any place on Earth to view the current UV radiation and 3-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.

The Forecast tab will display the next 7 days of UVI levels.

The accompanying widget will show the same information on your Today screen. The widget also displays helpful tips in order to best protect yourself from harmful radiation from the sun.

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.

Apple Health app:
The app will automatically store the maximum UV Index for your location, once each day, 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. Or, check the UVI any time right on your favourite watch face, using the included UVI complications. The UVI complication also supports time travel, scroll the wheel to check the UVI any time of the day.

The app will work anywhere in the world, and is a perfect companion whether you are at home or travelling.


The UV Index scale used in this app conforms with international guidelines for UVI reporting established by the World Health Organization.

Very Good App

This is a very good app. Works all over the world. If I could see the ACTUAL uv index in real time, instead of a projected index assuming a clear day, it would be more useful. Also, it would be helpful to see a forecasted hour-by-hour projection. With these additional enhancements, I would definitely give the app 5 stars!


Added complication to the iWatch

I’ve had the opportunity to speak with the Dev, prior to the most recent update and the adding of the complication to the iWatch. Great communication from him and I’m very happy with the provisions of this app.

I really like this app. It is simple and uncluttered. The UI is intuitive. The fact that it is capable of adding UV Index data to the Health app is just icing on the cake. Awesome.

UPDATE: The recent update to fix the Health UV index data saving has actually broken it for me. The UV index is saved as being “0” every day since the app was updated.
