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 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 set a Sun Burn reminder, which will notify you when the risk of getting a sunburn is high.

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.

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.

Am very appreciative of this app - great that it reflects your location and there is an ability to notify if UV level reaches relevant rating - helps me manage time in the sun and even where the sun is not obvious but the UV levels are 3+ the app alerts to this

Difficult to predict based on their wheel

I downloaded 5 similar apps to test them all out, and I gravitated towards this one first because of the nice graphic. However, the rotating wheel, rotates in the wrong direction, and instead of showing you how the UV index increases throughout the day and decreases towards the evening, it is more binary, and will only show you first thing in the morning, midday, and late in the evening. That’s no good for me. I need to know during the daytime when it’s okay for me to be outside, but this app can’t tell you. Instead of going from green to Orange to read to purple, it can only go from yellow to purple and nowhere in between on those days when it is extreme. And in Sydney during the summer every day is extreme. It would’ve been nice if they allowed feedback from within the app, but obviously they are not interested, so I am better off forgetting this and moving onto the next app.

Thank you for the feedback! I’m actually working on an update these days that will allow you to drag the sun left and right on the top graph, that way you can check the UVIndex any time during the day :) And also a direct feedback button is coming :) Hope to see you keep using my app!

Basic function good

I could really use a display of what time of in the afternoon to expect that the uv index will descend from high to moderate level. It's about the only feature I would be happy to pay extra for.
This was my review a year ago. The app hasn't changed. I regularly swim in an open air pool and I have a very sensitive skin. I need to know in advance what time in the afternoon the UV level drops to low. Annual statistics for the current date would suffice.

Developer Response ,

Hi! This functionality was added in the 5.0 update. Press the "Forecast" tab. It will show you the hour-by-hour forecast for today, and the next 6 days (with the pro version). Look for green bars if you want to know when the UVI is Low :)
