TutorHub: A Mobile-Based Peer-to-Tutor Learning and Earning Ecosystem Using Kotlin and Firebase

The increasing demand for flexible and accessible learning has encouraged the development of mobile solutions that connect learners with subject-matter experts. This study presents TutorHub, an Android-based application designed to bridge students and tutors through a structured digital learning environment. Built using Kotlin and Jetpack Compose with Firebase as the backend, the platform enables students to learn topics, post queries, request live sessions, and access video or written solutions. Tutors can schedule sessions, provide solutions, and earn remuneration based on their engagement and student feedback. The system introduces a mutual scheduling mechanism that allows both stakeholders to negotiate session timings, ensuring adaptability and minimizing conflicts. The paper outlines the system architecture, workflow, data management, and real-time communication strategies. Experimental evaluation indicates that the platform delivers a seamless, responsive, and scalable learning experience suitable for modern education ecosystems.
