A “Life Operating System” (Life OS) is a personal dashboard or workspace designed to centralize the management of goals, habits, projects, tasks, finances, health, relationships, and knowledge in a single interconnected system. The concept draws on the metaphor of a computer operating system — just as an OS manages hardware resources and runs applications, a Life OS manages the resources of a person’s life and runs their workflows.

Notion became the dominant platform for building Life OS setups because of its flexible database system, relational properties, and template ecosystem. Users construct interconnected databases for areas like task management, habit tracking, journaling, reading lists, and project planning, linked together through relations and rollups. The Mac Power Users community thread linked above documents various approaches and architectures people have built, from minimal single-page dashboards to sprawling multi-database ecosystems.

The Life OS concept connects to the broader personal knowledge management (PKM) movement, which includes tools like Obsidian, Roam Research, and Logseq. Where PKM systems tend to emphasize note-taking and knowledge capture, a Life OS extends the scope to include action management, time tracking, and life design. The underlying philosophy is that externalizing mental overhead into a trusted system frees cognitive bandwidth for creative and meaningful work — an idea rooted in David Allen’s Getting Things Done methodology and extended by thinkers like Tiago Forte with his “Building a Second Brain” framework.
