## What is UV Index Widget?

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.

### 5/5 — Perfect for gingers

*2026-08-09, version 13.1.3*

If you’re a ginger, like me, this is the perfect app.  Helps you focus on the UV for the day with accurate forecasts in ways to understand graphs. Helps me to know whether to apply one layer of SPF50 or 6 layers 🤣. But seruously, a grwta app, good widgits and phone integration and timely notifications of When the uv is at its strongest and when it is time to come out.

### 5/5 — Helpful info

*2026-08-05, version 13.1.3*

I have the widget on my lock screen, along with Weather, to easily see what the conditions are b

### 4/5 — Really nice job …. except!

*2026-07-23, version 13.1.3*

Best such app I’ve found. but…
- IV widget isn’t accurate recently. It just now showed a UV higher than the daily peak shown in-app. 🤔 
- i wish it would notify at multiple UV levels instead of just one. 
- a “go get some  Vitamin D” notification would be nice when i haven’t met my goal by X  hours before sunset.

### 4/5 — One feature i think would be cool to see

*2026-07-19, version 13.1.3*

The app is great. One thing i think would be helpful is, on the dial that shows the uv if you could spin it to move along in time like you can with the white dot on the line. This way you can see what uv it is at what time OR what time it is when it is a certain uv level (if you know what i mean).

### 1/5 — Doesn’t work

*2026-06-30, version 13.1.2*

Doesn’t work on my
Watch or iPhone

### 5/5 — BEST IN ITS CATEGORY

*2026-06-26, version 13.1.2*

Made my life easier, healthier and more comfortable.

### 2/5 — Requires sensitive data

*2026-06-24, version 13.1.2*

You can’t use it for free unless you reveal your location data . Have to pay to say what town you’re in which would make it less intrusive. Would have thought paid version would provide more location accuracy rather then the free one. Harvesting data for some other purpose perhaps.

### 5/5 — Tanning

*2026-06-21, version 13.1.2*

Great for tanning I got a great tan this summer

### 1/5 — Crashing

*2026-06-15, version 13.1.1*

The phone app won’t stay open & the app on my watch reads 0.0 24/7…. Loved this app initially — paid for a yearly subscription & now it doesn’t work at all. 😩

### 1/5 — Will not open

*2026-06-11, version 13.1*

This worked great for two years and now the app will not even open!  I see not updates pending
