What does the green dot mean?

A green dot on someone's picture means they are using Kovo now, or were in the last 30 minutes.

The 30 minutes are there on purpose. People put their phone in a pocket between sets, and they have not gone anywhere.

The dot is on or off. There is no away, and there is no busy.

The dot never tells you what someone is doing. The line under their name does that.
