How Shade Works

How Shade works

Sensor + app = Shade

Our smartly designed sensor attaches to your clothes. It syncs with our app to give you all-day insight and alert you as you approach your daily UV limit.

What's my daily UV limit?

Everyone’s daily UV limit is different — Shade will enable you to find yours and fine-tune it to fit your life.

Professional equipment. Stylish package.

Shade was designed by doctors and scientists at Cornell University, yet is stylish enough to be mistaken for jewelry.

Precise enough to measure UV from lightbulbs

Shade has engineered a proprietary diode and advanced calibration to deliver ultra-precise measurements of UVA and UVB rays.

Every time you get 20% closer to your daily UV limit, the sensor vibrates and the app sends you a notification, so you know exactly when to take action.
