UV Index Widget & Burn Time

Personal UV guidance

• See current UV, risk level, a burn-time estimate and recommended SPF together.
• Check cloud cover, temperature, humidity and wind through Apple WeatherKit when available.
• Use hourly UV, a seven-day forecast, sunrise/sunset and protection-window guidance to plan ahead.
• Keep core guidance available with a clear-sky solar estimate when live data is unavailable.

Sun sessions & journal

• Start a session, leave the screen and return while the timer keeps running.
• Record duration, location snapshot, starting/peak/average UV, SPF and sunscreen state.
• Add notes and one optional local photo to a completed session.
• Review weekly facts, a recorded-day calendar and unlimited session history—without exposure goals or tanning targets.

Reminders, places & devices

• Set UV threshold alerts and sunscreen reapplication reminders.
• Swipe between your current position and saved places.
• Use the Apple Watch app to check UV at a glance.
• Optional Pro unlock adds Home Screen and Lock Screen widgets, trip planning and custom morning/evening notifications.

Privacy & safety

Session photos remain in the app's local storage. The app does not analyze or upload them, and deleting a session also deletes its photo. Optional anonymous product events and crash diagnostics can be disabled in Settings. Advertising providers may process a device identifier according to your consent and the privacy policy.

Burn times, vitamin D estimates and protection suggestions are estimates, not medical advice. Actual UV and skin response vary with cloud, ozone, reflection, application quality and individual factors. Use shade, clothing, sunglasses and broad-spectrum sunscreen as appropriate.
