Apple CarPlay's built-in pink wallpaper is perfect for those looking to customize their car. It's pretty easy to locate in settings and set up, too.

Wallpaper Engine costs $3.99/£2.99/€3.99, but for that you get over 700,000 wallpapers, and the peace of mind that your desktop needn't look lacklustre ever again.

The free Bing Wallpaper app lets you refresh your PC's background image every day with a new image curated by Microsoft.
