Work time planning

How do you plan your work time and your projects?
I currently have three different projects, one project with periodic meetings with the client for testing, the second with the boss and the client, and the third I do for myself.
I would like to find a convenient program manager so that you can manage several projects, indicate what needs to be done for each project, detected errors, planned deadlines, actual time spent on each project (accounting for hours per day, week, per month and for the entire project ).
It would also be nice if this program can synchronize data on the project, for example, found bugs and todo lists, between colleagues, but this is optional.
