Cloudy doesn't mean safe. Lumi reads the live UV where you're standing, then times your reapply to your skin type — 90 min for fair, 150 for dark. One tap to log it. Your weather app shows a UV number. Lumi tells you what to do about it. Lumi reads the real-time UV index for your exact location, then times your sunscreen to your skin type — not a generic "every two hours" rule. Tap once when you apply. Lumi handles the rest. WHY A TIMER BEATS A GUESS Fair skin loses protection in about 90 minutes. Dark skin holds it closer to 150. Lumi knows the difference and counts down accordingly, so your reminder arrives when your protection actually runs out. REAL-TIME UV, WHEREVER YOU ARE Live UV index powered by Apple Weather. Color-coded guidance tells you what to do at a glance: green means relax, yellow means protect, orange means act now. Works anywhere in the world. ONE TAP TO LOG Applied sunscreen? Tap once. Lumi records the time, captures the UV index at that moment, and starts your countdown. No forms, no fuss. REMINDERS THAT RESPECT YOU A notification when your protection wears off — worded for your skin type and today's UV. Nothing else. No spam, ever. Optional morning briefing gives you the forecast before you step outside. BUILD THE HABIT Daily streaks keep you consistent. Weekly charts show your UV exposure and application history. Monthly stats reveal your protection score, so you can see the habit forming.
