Abstract: Urban communities routinely discard reusable goods due to limited access to structured channels for redistribution. Many individuals and families, meanwhile, experience a shortage of basic resources that could be filled using existing surplus. This work presents a mobile application designed to enable peer-to-peer donation and exchange of household items, educational materials, wearable goods, and electronic equipment. The system supports listing, request handling, status tracking, and real-time messaging between participants, thereby transforming informal donation practices into a transparent and traceable process. Developed as a native Android solution using Kotlin, Firebase, and Retrofit APIs, the application was evaluated in terms of performance, usability, and user perception. Results indicate that the system supports efficient onboarding, rapid synchronization of data, and smooth communication with minimal user effort, making it well-suited for community-oriented digital welfare initiatives.

Keywords: Donation system, Peer-to-peer exchange, Android development, Firebase, Sustainability.
