One touch of the screen, and a simple, material like wallpaper will be procedurally generated, using just four solid colors, one for the background and three as overlapping layers.
Procedural generation means the properties of each layer (color, size, position, the way they overlap eachother) are totally random, every single time.

The wallpapers are tailored to your display's native resolution, and with 16,776,216 posible colors, and more than 6,957,863,795,736 (and counting) unique layer combinations, you will never run out of wallpapers to personalize your home or lock screen.

They say beauty is in the eye of the beholder, but with this huge number of possibilities, not every single wallpaper generated will be a keeper. The good news is, if you don't like the current one, all you have to do is just tap the screen again, and a new one will be generated.
It will not take long before the procedural engine creates something to your liking, then tap on of the buttons at the top, the wallpaper will be set on your home or lock screen or both, and also added to your collection.

Your collection contains all the wallpapers you have ever set on your screens, like a logbook.
From here you can change your home/lock screen to any of your favorite wallpapers, and of course, delete the ones you no longer use/like.
The collection is stored locally, so no need for an internet connection and no consuming of your data plan to access your wallpapers.

Permissions used and why:
