How I built it:
Built entirely in Bubble as a native mobile app with 4 main tabs: Home(Feed), My Activities (track joined/created events), Chats (coordinate with companions), and Profile (manage interests). The app uses Bubble's data types for Users, Activities, Responses, and Messages, with option sets for categories (Tennis, Chess, Running, etc.) and statuses (Open, Confirmed, Completed). I designed a cohesive purple-themed UI (#8F63E9) with rounded cards, pill badges, and Phosphor icons throughout. Key workflows include joining activities (creates Response records), creating new events, real-time chat messaging, and profile management. Demo data populates all screens to showcase the full user journey from discovery to coordination.
