You can shop for the perfect Christmas tree without leaving your couch or taking measurements around the house.
“The app is free and allows buyers can browse through the department store’s range of real and artificial trees.
After selecting the one you want to try out, you’ll need to tap the “View in your room” button.
The app will need access to your camera, which you will need to point at the floor and then moving it slowly from side to side to scan the room.
It uses augmented reality to gauge an idea of the size of the room and the objects in it so your tree is in proportion with its surroundings.” -The Sun
