EVENN: Neighborhood Services App

Mobile marketplace for sharing neighborhood services with time-based currency system

The project stems from an innovative startup's need to develop a technological solution that facilitates connections between people in the same neighborhood for exchanging services using time as a unit of value.

The mobile application manages a geolocalized marketplace where users can offer or request diverse services, from tutoring to home maintenance. The system includes integrated chat for managing negotiations, calendar for organizing commitments, and social board for sharing advice.

The platform supports transactions both through internal time tokens and traditional payments, offering users flexibility. It includes a back office system for content moderation, conflict management, and advanced analytics.

The goal is to create active communities that value local skills and foster neighborhood relationships through digital tools.

Because time is the most democratic currency that exists.
