The live UV index on your Wear OS watch

Wear OS doesn't include a live UV index by default, but the T&T app adds one to your wrist. Open T&T on your Wear OS watch to see the real-time UV index for your location instantly — without pulling out your phone.

Yes. T&T is a tanning app with a dedicated Wear OS app. It shows the live UV index, runs your personalised safe-tan countdown, lets you start and stop a tanning session from your wrist, and taps you with a gentle haptic when it's time to flip. The watch apps are part of T&T Premium.

T&T runs on Wear OS smartwatches, including modern Samsung Galaxy Watch and Google Pixel Watch models. As long as your watch runs a current version of Wear OS and is paired with your Android phone, you'll get the live UV index and on-wrist tan timer.

Once a session is set up, the T&T Wear OS app shows the current UV index and your countdown right on the watch face, and buzzes you when it's time to flip — so you can leave your phone on the towel. Your session and Premium stay synced between watch and phone.

Yes — T&T offers the same experience on Apple Watch, with the live UV index, safe-tan countdown, and flip haptics. Whether you're on Wear OS or Apple Watch, your data stays in sync with the T&T app on your phone.
