This report presents the development of "League of IITB Legends," a comprehensive time management application tailored for the students of IIT Bombay. The project is motivated by widespread observations of students struggling with time management, leading to underperformance despite high motivation levels. The application integrates the principles of Fogg's Behavior Model and the Transtheoretical Model (TTM) to address various stages of behavioral change, from precontemplation to termination. The design process involved extensive primary and secondary research, including interviews and surveys with IIT Bombay students, which revealed common pain points such as procrastination, distractions, and ineffective traditional tools. Based on these insights, five strategic design interventions were developed: awareness posters with QR codes, seamless integration of academic data through LDAP login, personalized task scheduling, timely notifications, and a reward system with mentorship opportunities. Each intervention targets specific stages of behavioral change, ensuring a comprehensive approach to improving time management skills. The application aims to guide students through a journey of consistent improvement, providing the necessary support and motivation to adopt and maintain effective time management habits. The report details the theoretical foundation, design interventions, and anticipated outcomes of the "League of IITB Legends" application, positioning it as a crucial tool for enhancing academic performance and overall well-being among IIT Bombay students.
