NEW: D Reserve — your vitamin D battery. See how much of the sun you've banked is still working for you, and how many good sun days you have left before winter arrives. Your skin is unique. Your sun exposure should be too. Sola personalizes sun exposure recommendations based on your actual skin type. Sola is built for everyone. HOW IT WORKS 1. Onboarding — You answer a few questions so that the app can learn you. In this way, it can recommend how much time you need in the sun and if you need to supplement. 2. Get your daily session — a personalized time recommendation based on your skin type, real-time UV index, and local weather. 3. Track and improve — monitor your vitamin D journey with daily scores, weekly trends, and monthly reports.
