In an effort to redesign its mobile app to better serve larger and more complex organizations, Linear decided to create its own version of Apple's Liquid Glass design language, introduced at WWDC by Apple, rather than fully adopting Apple's APIs. This decision was driven by the need for a customizable navigation experience that could adapt to various user roles within the platform. Despite the challenges of having a small iOS team, Linear's approach involved developing a unique design system inspired by Apple's ProKit, which prioritizes clarity and control over visual flourish. The team focused on creating a tactile and visually responsive interface with real-time lighting effects and customizable elements like the tab bar, which allows for more navigation flexibility. By owning their materials and implementing accessibility features, Linear aimed to maintain a sense of depth and clarity without compromising user experience. This redesign marks the beginning of a broader architectural overhaul to accommodate Linear's growing user base and diverse usage needs, signaling a shift towards more adaptable and customizable tools in the future.
