Amazon Chime lets you meet, chat, and place business phone calls with their secure application. Amazon Chime offers pay-per-use pricing which lets you pay for features you use, on the days that you use them. Features include read and delivery receipts, file attachments, image preview, quote message, notification settings, persistent chat threads across all your devices, and the ability to adjust font size. For larger meetings, the Visual Roster provides attendee status including who is present, running late, invited, left, dropped and declined. If users don’t have the Chime app they can join using their web browser.
