Sunly: UV Index & Vitamin D

See the UV where you are, find your safe sun time, and track your vitamin D. Sunly helps you enjoy the sun and avoid sunburn every single day.

Sunly helps you enjoy the sun safely. See the UV index where you are, find the best time to go outside, track the vitamin D you get from sunlight, and get a reminder before you have had too much sun. It is simple, clear, and made for your skin.

Know Your UV Anytime See the real time UV index for your exact location, along with an hourly forecast for the rest of the day. Sunly updates as conditions change, so you always know how strong the sun is right now and what to expect later.

Find Your Safe Sun Time Everyone's skin reacts to the sun differently. Sunly uses your skin type and the current UV level to estimate how long you can stay outside before you risk burning. Start a sun session and follow an easy countdown.

Track Your Vitamin D Sunlight is how your body makes vitamin D. Sunly estimates how much you get during each session and shows your progress toward a daily goal, so you can get enough without overdoing it.

Get Sunburn Alerts Sunly lets you know before your safe time runs out. Set reminders to reapply sunscreen or move into the shade at the right moment, and get a daily nudge to check the UV before you head out.

See the Best Sun Window Sunly finds the best part of the day for healthy sun exposure and shows it at a glance, so you can plan a walk, a workout, or a break outside.

Home Screen Widgets Add a Sunly widget to your Home Screen to see the UV index, the best sun window, and your vitamin D progress without opening the app. Pick which saved city each widget shows.

Live Activity When you start a session, Sunly shows a live countdown on your Lock Screen and in the Dynamic Island, so you can keep track of your time in the sun at a glance.
