It is inspired by Sherlock’s 'crime board', pinning photos and notes, then connecting them with red strings. Todofi lets you do exactly that, and much more. Todofi helps you organize your notes using a tree-like outliner where notes can be nested within one another. From there, you can use the Whiteboard to map relationships between ideas, Kanban to track progress, Calendar to manage your schedule, and Maps to visualize locations.
