Track UV Index, optimise Vitamin D and sun-expose safely—with one tap.
UV Siesta is your smart sun-exposure timer that personalises every minute to your skin type, location and today's UV Index. Get vitamin-D insights, sunburn-risk alerts, SPF tips and enjoy the sun—skip the burn!

Why UV Siesta?
Too little sun leaves you Vitamin D-deficient; too much raises sunburn & skin-cancer risk. UV Siesta balances both—using live UV data and peer-reviewed models to show when, how long and how safely to tan.
