Scientific Sun Exposure Timer

Scientific Sun Exposure Timer calculates your safe daily sun limit by combining real-time UV Index, your Fitzpatrick skin type, and your phone's ambient light sensor. Whether in direct sun or shade, it dynamically adjusts your exposure time and alerts you with an alarm when it's time to seek shelter.

Protect your skin, prevent sunburn, and optimize your healthy Vitamin D synthesis safely with smart, science-backed outdoor tracking.
