Stay safe in the sun!
Sun Safe is an alarm countdown app to estimate how long you can safely stay in the sun.
The countdown is based on the current UVIndex for your location, your environment, cloud cover and which SPF sun screen you have chosen.
You can set multiple alerts for the countdown.
There is also some useful information for common sun safety questions.
