Skin cancer is one of the most common cancers, but also one of the most preventable. The UV Index provides a daily and hourly forecast of the expected intensity of ultraviolet (UV) radiation from the sun, as well as sun safety tips, to help you plan your outdoor activities. Some exposure to sunlight is enjoyable. However, too much sun can be dangerous. Overexposure to the sun's UV radiation can cause immediate damage, such as sunburn, and long-term problems, such as skin cancer and cataracts.

It is important to remember that people of all skin types need to be protected from overexposure to the sun. Make checking the UV Index part of planning your day and remember to slip on a shirt, slop on some SPF-15 + sunscreen, slap on a hat, and wrap on sunglasses to protect against the sun.

The UV Index is brought to you by EPA, the National Weather Service, and The Centers for Disease Control and Prevention.

Useful but there are glitches

The app is very useful, especially the hourly forecast, but the daily map has some technical issues. First, one cannot read the scale on the map; second, the dates for the maps change when the orientation of the ipad changes from portrait to landscape; third, the map is rather small and cannot be enlarged on the screen.

It's good, however....

This is a good UV index app however there certain days where I just cannot access the hourly and daily uv index using my current location. I keep trying to delete and download the app but just doesn't want to work at times once in a while. Today is one of those days where it just doesn't want to work. Please find a way to fix these bugs or I will no longer use

please update this app !!

would be 10 stars for sure if i didn't keep getting "forbidden access" error messages every time i click anywhere on the screen -- it works 10% of the time -- but when it does .. IT IS AMAZING ! this app has the potential to negate having any other UV Index apps ... PLEASE UPDATE for bug fixes !!!
