UV Tan Timer & Sunburn Guard

Get your exact UV index right now! Tan timer, burn time calculation, SPF recommendations and Vitamin D tracking — everything for a safe summer.

Take control of sun exposure and tan safely. Real-time UV index, personalized burn time calculation based on your skin type and a smart tanning timer — everything you need to enjoy the sun without risk.

Personalized Sun Safety for Your Skin All calculations are based on your Fitzpatrick skin phototype. The app determines how quickly you can get sunburned, what SPF you need and how long it is safe to stay in the sun. Take a quick test on first launch — and all recommendations adapt to your skin.

Even Tan Without Sunburn The tanning timer calculates safe time for each side of your body — front, back, left and right. Get notified when it is time to flip for an even, uniform tan. Swimming mode accounts for time in the water, and selecting your applied SPF automatically adjusts session duration.

Vitamin D & Sun Exposure Track your Vitamin D production and monitor time in the sun with Live Activity right on your lock screen and Dynamic Island. The app helps you find the balance between the benefits of sunlight and protection from harmful exposure.

Smart Notifications Set up alerts for high UV levels and reminders to reapply sunscreen. Get warnings when it is time to seek shade — without having to constantly check the app.

UV Index Worldwide Check ultraviolet levels in any city. Add multiple locations to track UV at home and while traveling. For each location — weather, time zone and multi-day UV forecast.

Download the app and feel confident in every minute under the sun Prevent sunburns, track sun exposure and maintain a healthy balance between tanning and Vitamin D. Enjoy the sun with confidence.
