What Day & Night is
Day & Night is a macOS wallpaper app that changes desktop backgrounds according to a time-based schedule. Its free plan supports timed wallpaper changes and custom refresh intervals. The app also supports live wallpapers, automatic rotation, and performance controls.

Premium costs $0.99 as a one-time in-app purchase; the free plan costs $0.00. Day & Night is available through its Mac App Store page. The free tier covers scheduled changes and refresh timing, while Premium extends customization and monitor support.
