Hello, Ahmed Mohsin

Hope you doing well.

Timesheets app:

Record the time spent by an employee over a project. Timesheets is a method of tracking employee working time. This Timesheets feature in Odoo, one can easily analyse the employee working report, says the project-based working time and task-based working time.

Planning app:

The planning module of Odoo operates based on calendar operations. In that user can configure the schedule of operations of a task or an associated project using the time and its functionality.

I hope it will help you.
