Todoist
Popular task manager with markdown in tasks and comments.
Todoist is one of the most widely used task managers, and its task names, descriptions, and comments accept markdown: bold, italic, links, lists, and code formatting all render inside tasks.
That lets you write task context exactly as you would notes — linked references, formatted checklists, inline code — consistently across its apps on every platform.
