Don’t fear the sun — master it. SunDose is your personal sun coach: an AI-powered health assistant that blends your skin type, location, and goals with real-time UV data so you get the right amount of sun — for vitamin D, mood, or a healthy tan — without burning or accelerating skin aging. WHAT MAKES SUNDOSE DIFFERENT • Real-time UV tracking — Live UV index, solar angle, and ozone data for your exact location. No guesswork. • Science, not guesswork — We use the WHO Standard Erythema Dose (SED) model, the same metric used in clinical UV research. Our methodology is patented and backed by dermatology expertise. • 6 personalized modes — Vitamin D Boost, Natural Tanning, Skin Protection, Enhanced Mood, Skin Rejuvenation, and Outdoor Activity. Each mode gives you a step-by-step routine tailored to your goal. • Smart session timer — A countdown that adapts as conditions change: clouds, added sunscreen, or different exposure areas. Alerts you before you approach burn risk. • Your skin, in the equation — Fitzpatrick skin type (I–VI), SPF, clothing, and body surface area all factor into your safe exposure window. Track daily, weekly, and monthly UV load on a clear calendar view. • One app for the whole family — Create profiles for yourself, your partner, and your kids. Each profile has its own skin type, goals, and history. • Sunscreen recommendations — Find and compare products that match your skin type, age, and environment. SunDose suggests the right product at the right time. • Live tracking & alerts — Color-coded skin load indicators and audible alerts so you stay within safe limits. Optional alarms keep you on track even when the app is in the background. Sun in moderation for maximum health. Download SunDose and start your first smart sun session today. Subscriptions SunDose offers auto-renewing subscriptions. Payment is charged to your Apple ID account at purchase. Subscription renews automatically unless canceled at least 24 hours before the end of the current period. Manage or cancel in your App Store account settings.
