This application is a Kotlin-based app utilizing ARCore technology to help users accurately measure room dimensions and place 3D furniture models directly in a virtual space. With the AR measurement feature, users can easily determine the length, width, and height of a room simply by pointing their device's camera. Additionally, the app provides a selection of 3D furniture models that can be placed in real-time, allowing users to visualize how the furniture would look in their space before making a purchase or rearranging their interior. Designed to offer an interactive and realistic experience, this app leverages augmented reality to enhance interior planning and design.
