Overview
Lumen is a concept for a sleep companion that asks for one decision per screen. The product had to calm people down, not keep them scrolling.

The challenge.
Most wellbeing apps are full of streaks, badges and notifications. Lumen’s value is the absence of all that.
Objectives
01
One decision per screen, everywhere
02
A night-first interface that never glares
03
A design system small enough to stay consistent
Strategy
We designed the app from the bedroom outward: warm, low-contrast type, a single progress ring and no red anywhere. The identity is the ring.
Exploration and system.
Screens were tested in a dark room on full brightness. Anything that caught the eye too hard was removed, including our first colour palette.
Type
Inter at large sizes with relaxed line height for reading in low light.

The outcome.
A twelve-screen product, a component library and a small brand kit, designed together so the app and the brand speak the same way.
More work, from the same desk.
