DeepDo-Hierarchical To-Do App

① Overview

DeepDo is a hierarchical to-do app with unlimited task depth for task management and project planning.
Create subtasks within tasks and continue adding deeper layers without limit—DeepDo supports unlimited hierarchy so you can organize tasks the same way you think.

Most to-do apps only support two or three levels, but DeepDo lets you build deeply structured task trees.
This makes it ideal for complex projects, long-term plans, idea organization, and detailed checklists.

Task structures can be saved and shared with flexible options such as public sharing, group sharing, and password protection.
DeepDo works both for personal organization and team collaboration.

② Key Features

• Unlimited hierarchy
  
  Create subtasks within tasks and build deep tree structures without limit.



• Drag-and-drop organization
  
  Reorder tasks and change hierarchy by dragging items. Insert tasks before, as siblings, or as children.



• MAP view (structure visualization)
  
  View the entire task structure as a map. Vector rendering keeps even deep hierarchies lightweight and smooth.



• Structure sharing
  
  Upload task structures and share them publicly, within groups, or with password protection.

③ Core Functions

• Create To-Do lists and subtasks


• Copy, cut, and paste parts of the structure


• Reorganize hierarchy with drag operations


• Collapse or hide subtrees


• Split tasks for progress tracking


• Support for 46 languages


• Backup and restore task structures

④ Value (Numeric Field)

Tasks can have numeric values assigned to them, useful for tracking workload, cost, or progress.
Units can be customized (e.g., $, items, tasks, yen, man-hours). Only leaf tasks can hold values.

⑤ Use Cases

DeepDo can be used for many purposes:

• Project management

• Task organization

• Writing outlines

• Design notes

• Structure visualization

• Study planning

Even very deep hierarchies remain easy to understand because the structure is clearly visible.

⑥ What Makes DeepDo Unique

Many to-do apps only support two levels of tasks, limiting flexibility. DeepDo allows unlimited hierarchy and powerful structural editing such as copy, cut, and insert anywhere in the tree.

Combined with MAP visualization and drag-based editing, DeepDo provides a unique way to manage complex task structures.

⑦ Future Updates

Future updates will continue to improve flexibility and usability based on user feedback.
