Loona UI design & app screens

Loona is a sleep and relaxation app combining bedtime stories, soundscapes, and interactive 'color-by-number' style nightscapes designed to wind the mind down before sleep. It targets people who struggle to unplug at night.

The design is richly illustrated and atmospheric: immersive nighttime scenes, soft ambient audio, and a calming, low-light palette throughout. The interactive coloring activity is a distinctive engagement mechanic. It is a reference for sleep and wellness UX, immersive illustrated environments, and using gentle interactivity to ease users toward rest rather than stimulating them.
