The app uses real-time UV data from your exact location, your Fitzpatrick skin type, planned time outdoors, and environmental factors to calculate whether you'll exceed your skin's burn threshold.

Unlike simple UV index apps, it doesn't just show a number. It integrates UV exposure over your entire outdoor window using hourly forecasts, and factors in cloud cover, surface reflection (snow, sand, water, concrete), altitude, and medical risk factors like medications or skin conditions.

Features:
  • Instant YES/NO answer with safe exposure time
  • 48-hour interactive UV forecast chart
  • Fitzpatrick skin type quiz
  • Customizable location and time — check conditions anywhere
  • Daily smart notifications based on your outdoor schedule
  • Home screen and lock screen widgets with live data
  • Reapplication guidance
  • Apple Watch app with UV complication
  • Backed by peer-reviewed dermatological research
