T&T: UV Index & Tanning App

T&T is the UV index app that calculates your personal safe tanning window
using today's UV rays, your Fitzpatrick skin type, and SPF — so you get a
golden glow without the burn.

Check the UV index today before you step outside. T&T shows your current
UV rating, hourly peaks, and a 10-day UV forecast — so you always know
when the sun is safe for your skin.

——————————————————————
⏱ SMART BURN TIMER
——————————————————————
Set your skin type and SPF. T&T reads the live UV index and calculates
exactly how many minutes you can safely stay in the sun. A real-time
countdown tells you when to go in or flip over. Get notified before you
burn — not after.
