The latest update to the Amazon app has Augmented Reality functionality built it...so you can see how furniture will look in your living room before you buy it; or how a shirt will look on you. IKEA launched something similar last month.
Like the popular Pokemon go game, the app superimposes an image of the item over the image seen by your phone's camera. Point the lens in the dining room to see how the table will look with your wallpaper, or see how that comforter might look on your bed.
If you don't already have the Amazon app...you can download it for free on all devices.
