Get the summer glow without the burn. UV Buddy is a tanning coach and a sunscreen reminder in one. It reads the UV right where you are, shows how long unprotected skin can take it, and keeps a reapply timer running for everyone in the family. GUIDED TAN SESSIONS Start a glow session and the app walks you through it: sunscreen on first, timed front and back flips, a refresh break, then hydrate. The length is built from your skin type and today's real UV, so you stop guessing how long is too long. NEVER MISS A REAPPLY Every family member gets their own reapply timer with an alarm that actually cuts through. Mark it applied, duck into the shade, and keep your SPF streak alive day after day. YOUR TAN, TRACKED Choose a glow goal and watch the sun minutes add up toward it, session by session. Add progress photos and see the change over weeks instead of guessing. TODAY AT A GLANCE Live UV for your exact spot, the hours it peaks, a 7 day forecast, the best windows to tan, and roughly how long bare skin lasts before it burns. Heading somewhere sunny? Look up any city before you pack. YOUR SUNSCREEN REPORT CARD A monthly card showing what you applied, what landed on time, and what slipped, plus your full tan history in one place. BUILT FOR THE WHOLE FAMILY One profile per person, each with their own skin type, SPF and buddy character. Everyone's timers run at the same time, so nobody gets forgotten. ON EVERY DEVICE Home Screen widgets, Live Activities in the Dynamic Island, an Apple Watch app showing your timer, today's UV and your live glow session, Siri Shortcuts for hands free checks, and iCloud sync across your devices. PRIVATE BY DEFAULT No account needed. Your profiles sync through your own iCloud, and analytics are optional. Stop guessing. Stop burning. Start glowing.
