The platform connects people with similar interests. It is designed for active people wanting to explore new opportunities or for those who are new to a place and want to reach out to like-minded people.

A comprehensive design for at least the following screens is expected: - login / register - user profile and interests - landing page with recommended activities - search for activities - create activities
