How long until you burn? Personalized UV protection based on your skin type -- no weather API, just solar science. Know your personal burn time before you step outside. UV Index computes clear-sky ultraviolet levels from the sun's position and tells you exactly how long YOUR skin can handle the sun -- personalised to your Fitzpatrick skin type (I-VI). No internet needed. No tracking. "UV Index: 6" is just a number. "You burn in 18 minutes without sunscreen" changes what you do. That is what this app gives you. PERSONALISED BURN TIMES Select your skin type and get burn time estimates from published dermatology data. Fair skin (Type I) burns in 11 minutes at UV 6. Medium skin (Type IV) gets 50 minutes. Your skin, your numbers, your safety margin. SPF GUIDANCE THAT MAKES SENSE UV Index calculates how long each SPF level protects you based on current UV and your skin type. SPF 30 at UV 5 for Type II? Protected for roughly 3 hours. Simple, actionable, personal. WORKS WITHOUT SIGNAL UV Index uses solar geometry to estimate clear-sky UV via the WHO model. It works on aeroplane mode, on trails, at the park, anywhere you need sun safety most. UV ALERTS AT THE RIGHT MOMENT Set your personal UV threshold and get notified when UV is about to cross it. "UV reaching 6 at 11:15 -- apply SPF 30+" arrives before you burn, not after. DAILY UV CURVE See the full UV arc for today, hour by hour. Colour-coded from green (low) through orange (high) to purple (extreme). Plan outdoor time around low-UV windows. SWIPE BETWEEN LOCATIONS Just like the Weather app -- swipe between your current location and saved cities. Each page shows full UV data, burn times, and forecasts. LIVE WEATHER DATA When connected, Apple WeatherKit overlays real-time UV, cloud cover, temperature, humidity, and wind. Offline? The solar model keeps working perfectly. OUTFIT SUGGESTIONS & VITAMIN D Get what-to-wear advice based on UV and temperature. See how long you need in the sun for your daily Vitamin D dose, personalised to your skin type. SUNSCREEN TIMER Tap Apply, pick your SPF, and get a countdown to reapply based on your skin type and current UV. TRIP PLANNER Check the 7-day UV forecast for any destination before you travel. APPLE WATCH Check current UV and burn time from your wrist. FREE FEATURES - Current UV index (live + offline) - Personal burn time for your skin type - SPF protection duration calculator - Hourly UV timeline with colour-coded levels - 7-day peak UV forecast - UV threshold alert notification - Outfit suggestions and Vitamin D estimate - Sunscreen reapply timer - Multiple saved locations with swipe paging - Apple Watch app PRO UNLOCK (one-time purchase, just £1.99) - Home screen and lock screen widgets - Trip planner for any destination - Notification customisation (morning forecast, evening summary) No subscription. No tracking. No data collected. Your location is used only for local UV computation and is never transmitted anywhere. Skin cancer is the most common cancer in the US, UK, and Australia. 86% of melanomas are caused by UV exposure. Knowing your personal burn time is basic sun safety. UV Index puts that knowledge in your pocket, even without signal. Note: Clear-sky estimates based on solar position, enhanced with live Apple WeatherKit data when available. Actual UV may differ due to cloud cover, ozone, and surface reflection. Not a substitute for medical advice.
