Amazon Chime

Amazon Chime is a communication service empowering teams with an easy to use and totally secure platform for online meetings. Meetings start on time, they’re easy to join with a single tap or click, the visual roster shows who is participating, and anyone can mute background noise. It’s easy to participate, and you can join from anywhere. The free plan is limited to one on one chats, voice calls and video calls, and the message history is only kept for a maximum of 30 days.
