Home Design 3D is one of the more stable home design apps. You draw your room spaces in 2D or 3D. You then populate the space with furniture and other decor items. It has a database of over 1,000 items. You can also edit objects to change their shape. That helps you decide if that weird shaped couch actually fits. There is a bit of a learning curve. Otherwise, it works fairly well. It also works offline.
