I made this as a YC SUS side project as it was difficult finding time to chat with colleagues compared to in real life. This allows people to mark that they are ready to have a break, rather than scheduling something in the calendar, so can better work around people's schedules.
Works nicely on a phone, as you go and grab a tea and biscuit :)
Feel free to pop in and try it out in my room: https://virtualcoffeebreak.app/group/hello
