Sketchar

Sketchar is a mobile augmented reality drawing application that transforms any physical surface into a digital sketch pad. Using the camera of a smartphone or tablet, the app projects virtual outlines onto real-world surfaces such as paper, walls, canvas, or even large-scale murals. This allows users to trace over the projected image with real markers, paint, or other physical drawing tools, effectively bridging the gap between digital design and traditional hand-drawn art. The app is designed for a wide range of users — from beginners who have never drawn before to experienced mural artists working on commercial projects. One of its core functionalities is the “AR projection” mode, which calibrates the device’s camera to the surface dimensions and then overlays a chosen image or sketch. Users can select from a built-in library of templates, upload their own photos, or import designs from other apps. The app then adjusts the projection in real time as the user moves the device, maintaining alignment with the surface. This makes it possible to create large-scale artworks with precise proportions without needing advanced freehand skills. Beyond projection, Sketchar offers a structured learning environment for drawing. It contains over 1,000 detailed courses that cover topics ranging from basic shapes and shading to complex portrait techniques and perspective drawing. Each course is broken into short, manageable lessons with step-by-step instructions. The app also generates a personalized drawing plan based on the user’s skill level and goals, adapting the difficulty as progress is made. Users can practice by tracing projected guides and gradually reduce reliance on the projection as their confidence grows. The learning tracks are designed for both casual hobbyists and ser
