## What is Vitamin D Sun Tracker & UV?

Vitamin D Sun Tracker & UV shows when your skin can make vitamin D today, how long you can stay out before you burn, and how far you are from your daily goal.

The app combines live UV from Apple Weather with the sun's angle at your location, your skin type, age, clothing and sunscreen:
- Sun window: the best time today for vitamin D.
- Burn timer and SPF: how long you can stay in the sun with your skin and sunscreen. Burn alerts arrive with the app closed.
- Live sessions: tap Start and watch your vitamin D add up, with a Live Activity on your Lock Screen.

Today's Sun Plan
- A plan for the day built around your skin, your goals and the UV forecast.

Sun and supplements
