ELEC 3: APPLICATION DEVELOPMENT USING ANDROID PLATFORM

Abstract
Randomize is an user-friendly and multifunctional application designed to simplify the process of
generating random outcomes, making it an invaluable tool for educators and group organizers. The
app offers robust features for randomizing numbers, names, and group assignments, catering to
various educational and administrative needs. Teachers can effortlessly create randomized numbers,
assign students to teams, or select participants for classroom activities, promoting fairness and
engagement. With its user-friendly interface and customizable options, Randomize streamlines
decision-making, reduces bias, and saves time, empowering educators to focus on fostering
interactive and dynamic learning environments.
