Mr. Tan

This summer you tan. You don't burn. You know the feeling. One day too long in the sun and you're red, peeling, and back to pale within a week. Or you play it safe and go home as white as you arrived. Either way: good sun, wasted. Mr. Tan is the cheat code for the perfect tan. It tells you exactly how long you can stay out today — for your skin, in your spot, right now — without burning. No more guessing. One number: your safe time, in minutes. Most weather apps hand you a UV index and leave you to figure out the rest. Mr. Tan does the math. Live UV, sun elevation, your skin type, your protection, your acclimatization, your medication — all folded into a single number you read at a glance. When your time is up, the app tells you to get in the shade. That simple. WHY YOU'LL WANT IT Know how strong the sun is right now — live UV and sun elevation, the second you open the app. A sun time that's actually yours. Built around your skin type (Fitzpatrick I–VI), your factor (SPF 6 → 50+), your cream, oil, spray or stick, your acclimatization and your age. Not a one-size-fits-all rule. Start a session and let Mr. Tan do the counting. It taps you on the shoulder when it's time to reapply, turn over or drink water — at calculated moments, not options picked from a dropdown. Eyes closed, phone down. The app speaks up: "Time to reapply." "Turn over." "Drink water." Going away? Plan your trip and see, day by day, how strong the sun gets and when you'll tan best — with peak UV, your best window and days remaining right on your home screen. See at a glance when the sun is worth it without the dangerous midday peak — and when you've caught enough for your vitamin D.

Always avoid burning, use sun protection, and consult a doctor if you notice unusual skin changes or suspect sunstroke.
