Can you recommend an app for managing your own projects?

Question

CRM

Have a nice day, everyone.
I am looking for a program to manage my own projects.
We wanted the following for the program:
1. You can run your own small projects: create tasks and subprojects, set deadlines, see the progress of implementation, and so on.
That is the usual functionality of a scheduler with a calendar.
2. The presence of a "board", or a panel on which different objects could be placed: notes, drawings, links, diagrams, and so on, to establish a relationship between them, and so on.
3. Ability to attach files, documents, links, images and so on.
Thus, it turns out something like a mixture of mural.ly and Evernote.
Maintaining customer information, invoicing, payment tracking and teamwork is not required.
I would be very happy if you can help in some way.
