## Description

Track vitamin D, sun safety & circadian rhythm with live UV, personalized exposure modeling, and Apple Health sync for sleep, body metrics & vitamin D.

SunMax turns sunlight into science-based guidance for vitamin D and safer sun exposure.

Using real-time UV data, a personalized profile, and a multi-factor model built around your skin type, exposed skin, sun angle, session timing, and weather conditions, SunMax helps you plan outdoor time more intentionally.
