Sun Alert

With Sun Alert you can calculate the maximal sun exposure time from your iPad, iPhone or iPod touch.
Whether you are at the beach, climbing mountains, skiing, walking, jogging or working outdoors you need to protect your skin from the UV radiation and thereby lower the risk of adverse health effects.

Select your skin type, the Sun Protection Factor (SPF) of your sunscreen and the environment. Sun Alert will retrieve the near-real time data of the UV radiation for your location and calculate the time you can safely expose to sun. Alternatively, you can use it to select the SPF of your sunscreen to meet a desired exposure time.

For more precise calculation, use the horizontal slider to set desired start time or the vertical slider to set a UV index limit. If you are using iPhone or iPod, turn the device in landscape mode to do this.
