Help me choose my Zoho tools

Help me choose my Zoho tools

I want to start a project where I am checking up on a rather large team. This means that different tasks will be assigned to every single person and notifications needs to be constantly shoot to track the progress of these people. I would like to know which is the best tool on the zoho unniverse that can help me with that functionality.

I use Google Calendar a lot, so a plus would be if it integrates with Google Calendar.

A simple example of what I am trying to do, is like trying to lend people to different periods and I need reminders on every deadline.
