DeepDo

Organize tasks with unlimited hierarchy. Manage complex projects with a flexible structure and collaborate easily with sharing features.

App Overview

DeepDo is a simple yet powerful todo app that lets you organize tasks in a hierarchical structure.
Create subtasks within tasks and add deeper levels to build structures as complex as you need. From organizing ideas to managing projects, everything can be handled in a tree structure that follows your thinking.
Save and share task structures for handoffs, expanding task lists, and visualizing structure—whether you're working alone or with a team.

About Value (Numeric Field)

Value is a numeric field you can assign to todo items. Units can be customized in settings (e.g., $, items, tasks, yen, man-hours). Saving files with appropriate units expands how you can use DeepDo.
Only leaf items can hold numeric values.

Developer's Intent

DeepDo is designed for people who think in structures. It shines when tasks are treated as trees rather than simple lists—in architecture, design, writing, learning, research, and similar fields.

What Sets It Apart

• Unlimited task hierarchy
• Flexible editing with copy, cut, and insert at any level
• Progress and workload visibility using numeric values
• Map view for seeing the entire structure at a glance

Future Updates

• Continuous improvements for the iOS version
• New features based on user feedback to make the app more flexible and powerful
