LayoutStudio is a focused visual workspace for designing and reviewing native asset layouts before implementation. Build visually Add titles, descriptions, advertiser labels, icons, main images, calls to action, ad labels, privacy elements, custom text, and boxes. Move and resize each asset directly on the canvas, then enter exact position and size values when precision matters. Preview in context Switch to a clean preview without editing controls. Try neutral colors, gentle gradients, a local image, or built-in mock templates as the background. Adjust zoom and canvas presentation to check whether the layout feels natural in its intended surroundings. Keep your work moving Save projects locally, reopen saved work from the project list, and recover the latest draft after an interruption. Coordinates and sizes remain part of the portable layout document so the design stays consistent across different displays. Designed for focused work Optional grids, snap-to-grid, undo and redo, image scale options, a clean full-screen preview, and draft recovery help you iterate without unnecessary setup. Image selection uses the system picker, and project content stays in the app's local storage unless you choose to share an exported preview. LayoutStudio is a layout prototyping and review tool. It does not request, bind, validate, or serve native ads inside the editing canvas.
