No-install, no sign-in is amazing. Appear is one of the services I've referred people to the most, for just that reason.
The main critique I have is their push to monetize as of late has been clumsily executed in my experience of the product. The expanded "pro" features have shifted around without enough heads up. The chatroom ownership system is not at all clear in how it interacts with paid accounts. We abandoned a few rooms used widely in our org until we figured out whose random account we had used to own a room earlier (from a prior push by Appear for room ownership) and got ownership transferred to a paid account.
