BookBoy is a mobile app that aims to create an easy platform for students to buy, sell, and lend books. The app will allow registered users to search for books from other users or vendors, quote prices, and finalize deals. It will track sales to generate revenue from wallet payments, vendor registration fees, and premium services like delivery. The target consumers are students and exam preparers, with goals of 1000 active users, 100 vendors, and 1000 deals in the first year.
