UV Index App

Know about how long you can stay in the sun with the UV Index app. The EPA or TEMIS's forecasted UV Index is automatically obtained based on your current location. Select your skin type, sunscreen's SPF, the local terrain (park, beach, city, skiing, etc.) and cloud cover and the app will calculate how long you have in the sun before skin damage occurs. Tap the UV Index icon to flip between the calculated maximum and the estimated current index for the day.
Remember that all these variables are estimates based on predictions and your safe time in the sun can be significantly shorter!

Setting Your Conditions

Type IV: Dark skin

Some cloud cover, but mostly sunny
Mostly cloudy skies

SPF

Select the closest SPF for the sunscreen you're using. Select "0" if you're wearing no sunscreen.

Set Time

Use this feature to remember the time you're suppose to get out of the sun. Let's say you go to the beach at 9:00 AM and the UV Index app suggests you seek shade by 2:40 PM. Click "Set Time" and the next time you run the UV Index app (that day), you'll see a reminder that you're suppose to get out of the sun by 2:40 PM.
