Analyse de l'application UV Index Pro pour le 15 mars

UV Index Pro is an easy-to-use application that displays the maximum and the current values of the ultraviolet index. This accurate measuring tool (portrait orientation, Android 6 or newer) works on the tablets and smartphones that are connected to the Internet. At first, it gets the local coordinates (latitude and longitude) from your device's GPS and then retrieves the UV index from an Internet server. The value of this index is given according to the international standard and represents the strength of the sunburn-producing ultraviolet radiation at your location (its current intensity). However, the real UV index depends on many factors, such as the angle of the Sun in the sky (current hour), stratospheric ozone, cloud conditions, and air pollutants. More importantly, you have to know that the reflection from snow or other bright surfaces like water, sand, or concrete can nearly double this index. This app features four big buttons on the first page, and their functions are (left to right): 1. Update location: re-read your current location and show the updated index. 2. Protection: shows a few important recommendations for protection, very useful in case you are exposed to sunlight. 3. Forecast: shows the graphs of the estimated UV indexes for the next five days. Pan left-right to see the hourly levels. 4. Vitamin D: shows the graphs of the estimated Vitamin D intakes. Pan left-right to see the total intake for the respective hours, assuming maximal sun exposure.
