This document provides an overview of the ClimberzzAssist mobile application, which is designed to help mountain climbers plan and navigate hiking trips. The key features of the Minimum Viable Product (MVP) include crowdsourcing reviews from other climbers, planning trips in advance, and using offline maps and GPS tracking while hiking. Future versions may incorporate health tracking, audio directions, emergency calling, and social media integration. Use cases and flow diagrams show the planning and on-site hiking experiences. Entity-relationship diagrams outline the user, mountain, route, review, and media data. The architecture will have presentation, application, and data layers, storing local data for offline use and connecting to backend services.
