What services are there for managing small tasks?

Question

Project management

Hello dear experts. )) Need a service or program to work together on small tasks.
Example: I create a task to join a VK group, someone takes the task to work and completes it. If the task is in progress, naturally no one else should perform it, unless of course it is for only one performer.
One of the important points is that you need to manage tasks strictly according to timing.
What are the most suitable task managers for my case or maybe I need something else?
Tell me please.
