Is there a good Android app that lets you create detailed interior design plans from scratch?

Planner 5D is a robust home design platform that excels at creating detailed interior layouts from the ground up. The app's core strength lies in its dual-mode editor, allowing users to switch seamlessly between a 2D blueprint view for precise spatial planning and a 3D walkthrough mode to visualize the final result. Specific features like real-time dimension labeling, an extensive catalog of brand-name furniture and appliances, and material customization for floors and walls enable users to experiment with different design schemes thoroughly. This is particularly useful for homeowners planning renovations or new builds, as they can test layouts, check traffic flow, and create a cohesive visual plan before making any purchases or starting construction. User reviews consistently praise its stability with large, detailed projects compared to competitors, though some note a limitation of three floors per project, which can be a constraint for very large or multi-story commercial designs. The app also supports exporting high-resolution images and videos, making it easy to share plans with contractors, family members, or on social media. While the free version is generous, a subscription unlocks the full item catalog and advanced editing tools. For a free-form digital design tool that balances professional-grade detail with approachable usability, Planner 5D is a strong contender.
