Headline: Your life needs an index. Tree adopts a minimal hierarchy to map your complex personal life into lightweight metadata. Stop trying to remember everything—use Tree to remember "how to find everything." Core Highlights: Metadata Mindset: Manage your life like clean code. Every node is a gateway to deeper information, condensing infinite complexity into an orderly directory. Dual-View Design: Canvas Mode: A God's-eye view. Zoom and pan on an infinite canvas to perceive the grand structure of your knowledge. Card Mode: Focus on the "now." Dive deep into specific branches and eliminate all external noise. Intuitive Interaction: Tap to expand, long-press for menus, and drag to reorganize. Every gesture is designed for pure intuition. Data Sovereignty: Markdown import/export with plain text storage. Your data always belongs to you. Why Tree? Cognitive Alignment: The human brain is naturally wired for hierarchy. Tree syncs with your innate cognitive patterns. The Ultimate Index: From root to leaf, our efficient retrieval logic guides you directly to your life’s milestones. Monochrome Aesthetics: Stripped of distractions, leaving only space for your thoughts. "The simpler the index, the vaster the world you command."
