Is there a service for splitting tasks into subtasks?

Question

Task Management

Actually I want to organize my activities and I wanted to know if there is something like a service in which you can set a task (goal), divide it into subtasks and so on in the form of a tree of tasks and subtasks in order to visually see the progress of execution, preferably cross-platform

Answer 1

Google any service with a Gantt chart .

Answer 2

MS Project (paid), Workflowy

Answer 3

If it’s just in the form of a tree, then any service for compiling mind-maps (mind-map), for example, XMind (free functionality for the eyes) or MindMeister (free only web-version), you can set deadlines and set other attributes in them, inherent in tasks. I can throw off a dozen paid and free services / programs for building mind maps . Bitrix24
has unlimited nesting of subtasks , but even in the free version it is overloaded with functions and heavy for quick mastering. Also take a look at Trello - there you can easily convert subtasks into main tasks, so there will also be unlimited nesting.
I have tried a LOT of taxers, probably almost all known ones, including all of the ones listed above.
My main requirement is unlimited nesting of tasks and visibility. Trello is one of my favorites right now.
