Apple Health Emotion Slider

This interaction showcases Apple's reflective state-of-mind logging in the Health app. As the user drags the slider from 'Very Unpleasant' to 'Very Pleasant', the central multi-layered, glass-like shape morphs its geometry, changing from sharp, complex purple petals to rounded, warm orange petals. Simultaneously, the entire screen's background gradient, the slider track, and the primary button smoothly crossfade to match the emotional tone. The text labels snap and crossfade to reflect the current state, creating a highly tactile and emotionally resonant feedback loop.
