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.

The app has some good information that can give you an accurate baseline, but it certainly has LOTS of room for improvement. Other than your location, there are ZERO personal factors taken into account. That might work well for some people, but I’m a natural redhead with light blue eyes and an extremely pale complexion, living in southern Florida, and I need an app that takes that into account. I read through all the EPA’s UV calculations, which consider wavelength, elevation, angle of the sun, ozone depletion, cloud cover, etc, but then only use some unknown “average” to calculate the sensitivity of human skin. Why bother being so accurate with your locational calculations to then turn around and assume every person is exactly the same? I really wish the EPA would realize that people are also as unique as locations, and that absolutely NEEDS to be taken into account.

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

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 !!!
