What's the best Android app for creating floor plans and visualizing home renovations before starting work?

House Design 3D Floor Plan App is a specialized tool for DIY home planners and renovators who need to sketch room layouts and visualize changes in three dimensions. The app's primary strength lies in its ability to quickly convert 2D floor plans into navigable 3D models. Users can place walls, doors, windows, and a sizable catalog of furniture from a built-in library. This functionality is particularly useful for scenarios like planning a kitchen remodel, where cabinet and appliance placement can be tested, or for figuring out furniture arrangements in a living room to optimize space. The app allows for adjustments to room dimensions and offers different view modes, including a first-person perspective to 'walk through' the virtual space. Reviews indicate that the 3D rendering, while not photorealistic, provides a sufficiently clear representation for planning purposes. A notable limitation is that the free version restricts access to the full object library and some export options, which can be a hurdle for more complex projects. The 2D plan editor is also described by some users as somewhat basic compared to dedicated CAD software. However, for quick conceptual sketches and client presentations for small contractors, it fills a specific niche. The interface, while dense with tools, is generally considered logical after a short learning period. Occasional stability issues on older devices have been noted in user feedback, but updates have addressed many of these concerns. For a free-to-start application, it delivers competent core functionality for its intended use case.
