Is There a Client Communication Tool?

Voxer is a free walkie talkie app that you can text on without giving out your personal cell phone number. Another client communication tool that I really like is Honeybook. Canva gives you more flexibility than Google Sheets or PowerPoint and they're just, again, very easy to use. Big Vu has never heard of it but he says if somebody from Big Vu is watching, please tell me.
