Question: Can you suggest a mobile app that helps me create a 2D or 3D floor plan of a room using my iPhone?

If you want to use a mobile app to generate a 2D or 3D floor plan of a room from your iPhone, Room Scanner is a good option. The app uses LiDAR to scan a room and generate detailed 2D and 3D floor plans, with features like easy scanning, multiple views and the ability to switch between 2D and 3D. You can export your scans in formats that work with popular design software like Archicad and Blender.

Another good option is Room Planner. The app lets you create 2D and 3D floor plans, measure rooms and furnish interiors with products from manufacturers. It also has features like remote collaboration, detailed reports for material costs and photorealistic 3D visualizations. Room Planner is good for interior designers, home automation installers and anyone who wants to quickly redesign their home.

For a more advanced design experience, Foyr has a broad range of CAD, 3D and rendering tools through an interface that's designed to be easy to use. It's got a big library of products and inspirations so you can generate photorealistic 3D renders and 360 walkthroughs. Foyr also supports real-time AR design visualization and cloud-based collaboration, so it's good for pros and hobbyists.
