T&T: Tanning App, UV Index

Your skin, your limit. T&T reads live UV, builds your personal safe-tan window, and runs a burn timer that tells you exactly when to flip or cover up.

Know exactly when to stop tanning — before your skin tells you.

T&T tracks real-time UV index for your location and calculates a personal safe tanning window based on your Fitzpatrick skin type and SPF. Start the burn timer and get a notification when it's time to flip or head inside.

No sunburns. No guesswork. Just a smarter time in the sun.
