There are already apps like Meetup which help people 'meet up' with others, make new friends etc, but their purpose is not explicitly about making friends. Ultimately, though, getting yourself to an event with other people is only part of the problem, you still need to be able to connect with the people you meet, introduce yourself, have a conversation, bond. If you really want to create an app to tackle social isolation, maybe you could look at something that helps people improve their social skills instead, a sort of online tutor. There are definitely a lot of tricks to be learned to thrive in social situations, and while some people seem innately more equipped, I believe almost everyone can learn them to some degree.
