I asked perplexity.ai and it replied:
Apps like WallApp, PhotoFunia, and Wallary allow you to upload a photo of your room and then place your artwork or photo on the walls virtually to see how it will look.
ArtRooms and Voun offer similar features with options to choose frames, wall colors, and room settings, often with augmented reality capabilities.
PictureThat app uses AR technology to place photos at various sizes and layouts on your actual walls, giving you a realistic preview.
WallPictureApp also provides an easy way to see your photos or paintings in your space.
