UV Index + Sun Widget

Check the UV index before going outside. Get the current ultraviolet risk, a 24-hour forecast, seasonal trends and a home screen widget in one app.

The app calculates UVI for the precise place and time and shows exposure on sun-facing skin surfaces such as the face and arms. Advanced charts help you understand UVA, UVB and visible light beyond the standard UV index.

Key features:
• UV index for any location
• 24-hour forecast and seasonal trends
• Home screen UVI widget
• UVA, UVB and visible-light charts
• Daily UVI 3+ sun-protection window
• Optional live weather and cloud adjustment
• Offline support with the most recently saved data

Use the app to plan walks, running, cycling, hiking, beach days, travel and other time outdoors. See when UV is strongest and plan shade, protective clothing and broad-spectrum sunscreen around the day’s conditions.

No account is required. Location permission is optional, and you can choose a city manually instead. Saved locations remain in the app’s private on-device storage.

The values shown are modelled estimates for education and personal planning. This app does not replace medical advice, measured UV data, official weather alerts or product directions. Conditions can change quickly; always follow local guidance and practise sun-safe behaviour.
