Subspace
A fintech mobile app for card sharing, subscriptions, bill payments, and peer-to-peer transactions.
About the Project
Subspace is a fintech mobile application designed to simplify how users manage shared financial services. The app consolidates card sharing, bill splitting, subscriptions, rentals, and gift cards into a single intuitive interface.
The project explored how financial tools can feel approachable and social — moving beyond traditional banking UI to create an experience that feels native to how young users actually interact with money.
Core features include a Home dashboard with financial overview, Explore page for discovering services, Wallet for card management, Chat for peer communication, and dedicated flows for Bills and Recharges, Shared Subscriptions, Rentals, Gift Cards, Shop and Earn, and Card Share.
