Minimal apps are always the best, and Deko is a clear example of that. The free app for iPad and iPhone lets users randomly generate wallpapers for their device.
The app begins by giving you a random colourful wallpaper. From there, users can pull from the right to change the design. The further you pull the bar from the right, the more the design changes. For example, if you like the design but don’t really like the colour, you can only slightly pull from the right to change the colour.
Just about every design generated by the app is beautiful. Give it a try for free!
