Msg is a minimal web app that lets you silently flash short messages to people who can see your screen.
It's free, and doesn't store your data.
We developed Msg to allow parents to silently communicate without disturbing a child, in situations where quiet is needed. It has other uses, like communicating across a room without disturbing others, or voting situations like 'planning poker'.
