## What is Sun Exposure Timer?

Stay safe in the sun with a clear, local UV index forecast built around your skin.

• Live UV index now with risk level and plain-language advice
• Hourly UV plus a 7-day peak forecast for your location
• Time-to-burn estimate for your Fitzpatrick skin type
• SPF and clothing recommendations that match the current UV
• Sunscreen reapply reminders and a daily morning summary
• Vitamin-D window and a 7-day record of your UV exposure

Simple, fast and private. Plan outdoor time with confidence.

UV values are forecasts and estimates, not a skin measurement, and not medical advice.
