SunMeter UV Level

SunMeter — Personal Sun Timer

Know exactly when you'll burn — before your skin does.

Most UV apps show you a number and leave you guessing. SunMeter gives you a personalised countdown: your skin type, your SPF, your live UV right now — calculated into a single timer that tells you exactly how long you have before you need to get out of the sun.

Your personal burn time Set your skin type (or let AI detect it from a selfie), choose your SPF, add your hat or cover-up, and SunMeter calculates your precise time-to-burn. Not a generic recommendation — a countdown built for you.

Always visible on your Lock Screen (SunMeter Premium) Start a session and your burn timer lives on your Lock Screen and Dynamic Island all day. No need to open the app — just glance and go. Apple Watch support included.

AI skin type detection Not sure which skin type you are? Take a quick photo and the AI estimates your Fitzpatrick type automatically. The more accurate your type, the more accurate your burn time.

Live UV for your exact location (requieres SunMeter Premium) Powered by WeatherKit, SunMeter fetches real UV data for your precise spot every 15 minutes — not a city-wide estimate, not a forecast average. What's happening outside your door, right now.

Smart alerts before you burn (requieres SunMeter Premium) Get notified when it's time to reapply sunscreen, when you're approaching your burn limit, and when UV is peaking. Timed to your skin, not a generic schedule.

SunMeter Premium (it is a paid subscription) includes:

• Unlimited sun sessions
• Apple Watch app and widget
• UV forecast

Soak it in, safely.
