Overview
01
The challenge
Most sleep apps judge you in the morning. Lull’s founders wanted the opposite: a calm coach that plans a realistic evening and never shames a late night.
What we did
We designed the whole product around one screen, Tonight. A single ring shows your sleep window, the wind-down list fits on one thumb-scroll, and the coach only speaks when it notices a real pattern.

Identity

The icon, the palette and the type were designed together with the interface, so the app looks like itself everywhere: home screen, store, notification.

The unglamorous state

First night, empty state
The moment that decides whether someone trusts the app enough to open it again tomorrow.
