iPhone Duo is here! Excited to have worked on the design of our open/close transition. It’s designed to make the two displays feel like one seamless experience by perceptually bending the focal plane, not the content, so that it feels like opening a window onto a singular view.

Steve’s been my manager for my entire 15 year career so far at Apple and I could not be more excited for this new era.

.@Apple enters a new chapter in Human Interface Design as Steve Lemay becomes the new leader of the team, working alongside Molly Anderson, head of Industrial Design at Apple. A veteran at the company since 1999, Lemay has shaped every major interface evolution from the original #iPhone to macOS, iOS, iPadOS, watchOS and, most recently, visionOS.

Tim Cook calls him “an extraordinarily high bar for excellence,” noting his depth of understanding in platform technologies and his gift for shaping intuitive, human-centred digital experiences.

With Lemay now at the helm, Apple’s design bench continues to push forward, refining the interactions, systems and visual languages that define the world’s most recognisable devices.

The latest project I’ve been working on is the design of Liquid Glass, alongside an army of designers and engineers. We're designing it to bend and shape light while feeling like an elastic, flexible material that can dynamically shape shift, to make apps feel fluid and organic.
