Tennis: sort the court without the group chat
The court is booked by the hour and one person going quiet is enough to spoil it. Pudem asks for you, so you know if it's two or four.

What it sorts out
Small groups work too: set capacity to two or four and the rest are the waiting list.
Dates go into the phone's own calendar – Google, Apple or Outlook.
If it rains, cancel in one tap and everyone hears about it.
Questions
Does Pudem work for just two people?
It does. Set the capacity to two and the rest of the group waits – when one can't make it, the next moves up on their own.
