Procedural Wallpapers

Sometimes, less is more, simpler is better.

Get it on Google Play

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 possible 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, in its own folder inside your device's default Pictures folder, so no need for an internet connection, and no consuming of your data plan, to access your wallpapers.

Compatibility note: Lock screen support is only available on devices running Android 7.0 and newer, on older versions only system apps can interact with the lock screen.

Known issues:
- if your device has a scrolling wallpaper, this app may not work as intended, unless the scrolling can be disabled in the home screen settings.
- rotating home screens are not supported, the wallpapers are generated in portrait mode for phones and small factor tablets (7"), and in landscape mode for large factor tablets (10").

Current Version:
1.6

Requires Android:
6.0 and up

Procedural Wallpapers - ChangeLog

v1.6
Updated:
- switched from storing the wallpapers on the Procedural Wallpapers folder located in the public Pictures folder, to a private folder (therefore complying with the scoped storage access introduced in Android 10), your existing wallpapers will be migrated the first time you run the app after updating (keep in mind, from now on, you will lose your wallpaper collection if you uninstall the app)

Fixed:
- on some devices, the wallpaper was drawn offset to one side (left or right), and therefore did not fill/fit the home screen properly, use the new option Offset Drawing to mitigate this

Updated:
- dropped support for Android 5.1
