Mobile applications are software applications developed for small and wireless computing devices such as smartphones and tablets, rather than desktops or laptops. With advancements in networking technologies, mobile applications are increasingly utilized in the field of education, particularly in libraries, to engage more users. They are predominantly preferred for providing library services such as accessing e-resources like e-books, e-journals, e-newspapers, e-patents, etc. Additionally, these applications provide users with access at any time, from anywhere, and help save time. This paper briefly explains the design of a mobile application for Dr. GRD Memorial Library, the main library of PSG College of Technology, using Jotform, a free, no-code app builder that allows sharing multiple forms, links, and other elements in a single app that works on any device. To enhance interactivity, a chatbot is also incorporated using an AI chatbot builder, Chatbase, primarily utilized for adding chat widgets in mobile applications.
