Instead of an app I think we need to rethink our living arrangements. Where I live (Japan) living alone is the new norm. After I moved out of university dorms I've lived in little shoebox apartments with my own little kitchen, my own little bathroom and no need to cross paths with any of the other 100 people in my building at all. I see that a lot of the new apartment blocks around my city are full of small, single-occupancy apartments too. There are no communal spaces. There are no chance encounters. People seem to feel like there is too much risk in meeting new people, let alone dining with them. There have been some shared houses popping up here and there. But they are viewed as as exceptional and unconventional. Social interaction has become a peculiar character trait rather than a normal part of life.
