Early in the pandemic, I learned of an app called Dialup which offered a service called Quarantine Chat. They call my telephone at some random time every day, and I am connected to some other random Dialup user, somewhere else in the world.

Most often, conversations never moved past the awkward stage. I've not accepted calls from them for many months now, but I did have a few interesting/memorable conversations on the app, from people in my own city, to people halfway around the world.
