We present a mobile application designed to enhance students' understanding of directional derivatives and level curves in first year's calculus. The application offers visual tools and gamified learning to provide an engaging educational experience. Using novel technologies such the application is able to take a users drawing, generate a corresponding 3D model, and display this to the user. Through this presentation, attendees will gain a comprehensive understanding of the application's features and the benefits it offers to students in comprehending directional derivatives.@en
