The app is built for Android and is implemented in Java, which is a widely-used programming language for developing android applications. The application is designed to be user-friendly and intuitive, making it easy for customers to navigate and make purchases.

The database used in the application is PostgreSQL, which is a powerful, open-source object-relational database management system.

In addition to customers, the app also allows admins to create, update, and delete items, categories, and orders. This allows the store owners to efficiently manage their inventory and orders.
