## App Overview DeepDo is a powerful to-do app that lets you organize tasks and information in an unlimited tree structure. Create subtasks within tasks, and add even finer tasks within those, so you can freely structure complex content. From personal task management to project management, learning, design, and information organization, you can manage your flow of thought as a tree. DeepDo also supports AI-powered structure generation. Simply enter text or ideas, and complex content is automatically organized into a hierarchy. Created structures can be saved, shared, and exported as PDF. Use cases range from sharing procedures and expanding to-do lists to organizing knowledge and visualizing structure—for both personal and team use. ## Main Features * Add items (to-dos) * AI structure generation * Automatically convert ideas and text into a hierarchy * Support for project planning, learning content, and work procedures * Menu when tapping an item * Select: Open a page based on the selected to-do * Add list: Create a sub-to-do under the selected item * Edit: Change title / price (numeric value) / color * Save: Save the selected item and everything below it * Delete: Delete the selected item and its children * Cut / Copy: Include children; paste anywhere * Insert: Insert saved, cut, or copied items as children * Bulk insert: Paste text and auto-create one item per line * Progress split: Split a to-do with a value into children (original value is cleared) * Hide / collapse children (swipe shortcut) * Display in 3-level blocks (e.g. show levels 5–7; levels 1–4 in breadcrumbs at top) * Drag to reorder and organize items * Map mode: View the full structure; pan and pinch to zoom * Sharing mode: Online sharing via public, group, or limited access * PDF export: Save as searchable, copyable PDF * Backup to storage (folder organization supported) * Backup list: Share / overwrite save / insert / restore / delete * 47 languages (change anytime in settings) ## About Price (Numeric Values) Price is a numeric value you can set on a to-do item.
