Workplace Chat from Meta

The Workplace Chat app lets you keep in touch with your colleagues, wherever you are. Simply sign in to your existing Workplace account, or create one from scratch in the app itself.
 
With messaging tools your teams already knows how to use, Workplace Chat lets you:

 - Send messages to individual coworkers, or have group conversations.

 - Share unlimited files, photos and videos.

 - Make voice and video calls from your mobile or your desktop.

 - Turn on "Do Not Disturb" when you're busy or away from work.

Workplace Chat is ad-free and totally separate from Facebook and Messenger, making it easier to balance your work and private lives.
