Need a GTD organizer with a special feature?

Question

Time Management

I started optimizing the little things in my life: there are a lot of them, they need to be done, they constantly fly out of my head.
I started by using a to-do list: first on paper, then on a computer, now on a smartphone.
Tried many programs for Android. In principle, they all seem similar to me, no one stands out for me in particular. Everyone has tasks, ticks, deadlines, reminders… But in reality, I see the situation differently. Most tasks are not checkboxes and fads, they are chains.
Example - the microwave broke down:
Call the service, find out where and when -> Take it to the service -> (in two weeks) Call, find out if it's ready -> Pick up
And such tasks are almost all. Of course, you can simply constantly edit the same task, changing its due date and importance. It's not too bad, although the rendering suffers.
Maybe there is some program (not necessarily for Android) that can do this out of the box?
Or try to write it yourself?

Answer 1

Any task manager is suitable for you, where you can group tasks (create projects) for example doit.im

Answer 2

TaskCoach has the ability to set dependencies for tasks: until one is completed, the other is disabled. You can also nest subtasks.

Answer 3

For PC in linux there is Getting things GNOME! which initially conveniently collects topics in chains and works with tags. Look.
