Solaris: UV and Outdoor Health

Know exactly when to go outside — and how long to stay. Solaris is your daily outdoor health companion. Every morning you get a personalized outdoor health score from 0 to 100 built around your body, your skin, and the conditions outside your door. Not a generic weather forecast. A recommendation made for you. YOUR DAILY OUTDOOR HEALTH SCORE Every day Solaris calculates a score based on six factors that matter to your body specifically: UV index versus your skin type, air quality, temperature and humidity comfort, wind conditions, pollen levels, and weather. One number tells you whether today is a great day to be outside or a day to keep it short. THE BEST TIME TO GO OUTSIDE TODAY Solaris scans every hour of the day and finds your optimal outdoor window based on your activity, your skin type, and your personal goals. Whether you are running, cycling, walking, or gardening, the recommendation is built around what you are doing outside — not just what the weather looks like. VITAMIN D TRACKING Most people have no idea how much vitamin D they are getting from the sun. Solaris calculates your estimated IU in real time using your Fitzpatrick skin type, the current UV index, how long you have been outside, and which parts of your body are exposed. Tap start when you step outside and watch your daily total build. See your weekly history and track progress toward your 600 IU daily goal. BODY EXPOSURE SELECTOR Solaris is the only app that accounts for which parts of your body are actually in the sun. Use the interactive body selector to show whether you are wearing a t-shirt and shorts, full swimwear, or just exposing your face and hands on your daily commute. Your vitamin D estimate updates instantly. MORNING LIGHT AND CIRCADIAN RHYTHM Morning sunlight is one of the most powerful tools for better sleep, mood, and daily energy. Solaris tracks whether you got outside during the critical window after sunrise and gives you a Morning Light Score each day. Build a streak, see your weekly patterns, and understand how your outdoor habits are shaping your sleep. PERSONALIZED TO YOUR SKIN Solaris uses the Fitzpatrick scale — the medical standard for skin type classification — to personalize every UV recommendation. Fair skin that burns easily gets different advice than skin that rarely burns. Your safe UV threshold, your vitamin D production rate, and your sun damage risk are all calculated based on who you actually are. POLLEN AND ALLERGY ALERTS — PREMIUM Tell Solaris which pollens trigger your allergies and get warnings before you go outside on high pollen days. Alder, birch, grass, mugwort, olive, and ragweed are all tracked. When your trigger pollen is high you will know before you open the door. 7-DAY OUTDOOR HEALTH FORECAST — PREMIUM Plan your outdoor time a full week ahead. See your personalized health score for each of the next 7 days so you can schedule runs, outdoor events, and morning walks around the best conditions for your body. WEATHER AND CONDITIONS Solaris goes beyond temperature. Every recommendation accounts for UV index, air quality, wind speed and direction, humidity, cloud cover, rain probability, visibility, and WMO weather codes. If it is going to be gusty during your run or overcast during your vitamin D window, Solaris accounts for it. BUILT FOR YOUR GOALS Choose between maximizing vitamin D production or minimizing sun damage risk. Set your preferred outdoor duration. Select your activity type. Set your rain tolerance. Every preference shapes your daily recommendation so the advice you get reflects the life you actually live. — Solaris Premium includes the 7-day outdoor health forecast, pollen and allergy tracking, and full vitamin D session logging.
