Someone posts a slot: Litter picking, a time, a place, a number of spots.

Litter picking in Berlin
Alone you look odd. Ten of you look like a good idea.
And if nobody is there yet?
That is the normal state of a city starting out, not a fault. Two things beat waiting: post the first slot — whoever does finds someone fastest — or set an alert and let meetDo tell you.
It shows up on the map and in the feed of people who said they like litter picking.
You join with one tap. The exact address appears, the host is notified.
Nothing around you? Post your own, or set an alert: you will be told as soon as someone starts.
Meeting a stranger takes preparation
Tell someone, and get home
Before you leave you arm a watch: someone close knows where you are going and when you should be back. If you do not confirm your return, they are told. And if you have nobody to tell, the watch still works.
Public or private place
A private place only shows its address to people who have joined. Until you have, you see the neighbourhood, not the door.
What others see of you
One page lists every channel through which someone could observe you — and a button at the bottom cuts them all at once. Nothing in meetDo can see you without appearing there.

Something is happening three streets away
And someone there is looking for exactly what you are looking for. In the real world.
