Melanin Sun Ring is THE sunlight tracker built for your skin. Most health apps give everyone the same advice. But if you have higher melanin levels, your body may need more sunlight to produce Vitamin D — and generic guidance doesn’t always reflect that. Melanin Sun Ring was built to personalize sunlight tracking around you. Tell us your skin tone once, and we do the rest. Watch your Sun Ring fill up as you spend time outside. Your daily goal is calculated around your melanin level, your local UV index, temperature, and your location — so it’s never a random number. It’s yours. • A sunlight goal that’s actually personal Set your melanin level once. Every day your goal updates based on real UV conditions and weather where you are — not a one-size-fits-all recommendation. • The Sun Ring A beautiful progress ring that fills as you get outside. Sun exposure is tracked automatically through Apple Health and your outdoor activity — no logging, no manual entry, just go outside. • Know the best time to step out See today’s optimal sun window personalized to your skin tone. Stop guessing when to go outside — Melanin Sun Ring helps guide your sunlight exposure. • Your streak, your momentum Build a daily habit and watch your streak grow. Consistent sunlight exposure supports long-term wellness. • Live UV index and weather See today’s UV index, peak UV time, temperature highs and lows, and whether outdoor sunlight will be enough — or whether you should look at other sources. • Full history and yearly Sun Score Track your sunlight exposure over 7 days, 30 days, and the full year. See your best months and your lowest — and keep improving your sun habits. • Apple Watch companion Your Sun Ring, streak, UV index, and temperature right on your wrist. Check your sunlight progress anytime. Melanin Sun Ring is free to download. Premium unlocks live UV and weather data, your personalized sun window, history charts, yearly Sun Score, and full Apple Watch sync — all for a one-time $1.99. No subscription. No recurring charges. Requires Apple Health for outdoor activity and sunlight tracking. Premium features use location for live UV data. Melanin Sun Ring provides wellness estimates based on scientific research and is not a substitute for medical advice. Consult a healthcare provider for guidance specific to your health needs.
