Solaria: UV Index & Tanning

Solaria is a sun-safety and tanning app for iPhone. It combines the live UV index for your location with your skin type to show how long you can stay in the sun today — in minutes — and reminds you to reapply sunscreen during a session. Best for: people who want to tan but burn easily, parents watching their kids' sun exposure, travellers heading to a sunnier climate, and anyone tracking vitamin D from sunlight. WHAT SOLARIA ANSWERS • How long can I stay in the sun right now without burning? • Which SPF do I need today, and when should I reapply it? • Am I getting enough vitamin D from the sun this week? • Is it safe to sunbathe at this hour, or should I wait? HOW IT WORKS 1. Set your skin type (Fitzpatrick I–VI) and the shade you want to reach. 2. Solaria loads today's UV forecast for your location, or for a city you pick by hand. 3. You get a safe-time countdown and an SPF recommendation for today's UV. 4. Start a session and the countdown also accounts for the sunscreen you applied, time in shade and time in the water. FEATURES • Live UV index with hourly forecast • Safe-time countdown from your skin type, the current UV and your altitude • Background reapply reminders: 120 minutes after you apply, and right after a swim or shower • A heads-up at 80% of your daily UV budget, and again when you reach it • Tan progress toward the shade you choose • Vitamin D estimates that account for exposed skin and your skin type • Sun passport: skin type, body zones, moles with ABCDE notes • Photo history: line each new photo up with the previous one and compare dates • Skin recovery plan after sunburn or redness, with a countdown and after-sun care tasks • Achievements for safe sun habits AFTER A SUNBURN Got burned anyway? Log a skin check and Solaria switches to a skin recovery plan: a countdown until it expects your skin is ready for sun again, daily after-sun recovery tasks — water, cream, cooling the skin, staying in the shade — and a short list of what to avoid. Completed care tasks shorten the countdown; time in the sun during recovery makes it longer. HOW THE NUMBERS ARE CALCULATED The full formula is published, with every factor and its limits: solaria.madebynkt.com/guides/how-solaria-calculates-safe-time WHAT SOLARIA IS NOT Solaria is not a medical device and does not diagnose skin conditions or skin cancer. Safe time is an estimate built from a forecast and your answers, not a promise. The recovery plan is general after-sun care, not treatment. Reflection from sand and snow is not counted. For any mole or skin change, see a dermatologist. AVAILABILITY iPhone. English, Spanish, Portuguese, German, French, Italian, Polish, Russian, Ukrainian and Indonesian.
