It is a lamp that reflects your favorite images (person, place, scene, or picture) on the walls and ceilings. It designed with kids in mind, to light up their rooms at night while falling asleep.
The app can be used with an iPhone projector to display the apps images on a wall.
If you dont have a projector, then it also works perfectly by displaying the image on your phones screen.
Since its a night light, it auto-locks or sleeps after a certain time, depending on your timer preferences (20 minutes, 30 minutes, 1 hour, or more).
