Day & Night review
A focused macOS wallpaper utility with useful automation and a low-cost Premium tier.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Day & Night is a macOS desktop wallpaper utility for people who want backgrounds to change automatically throughout the day. It supports day and night states based on locally generated sunrise and sunset times, as well as custom refresh intervals and dynamic wallpaper sequences. Users can select images or drag them into day and night slots. The app requires macOS 10.12 or later and fits solo users and small teams looking for a focused desktop customization tool rather than a broad wallpaper library or design application.
The free plan covers the core automation: time-based wallpaper changes and custom refresh intervals. That makes it suitable for a simple day/night setup, while also giving users control over how often wallpapers refresh for power and battery considerations. Premium costs $0.99 as a one-time purchase according to the published US listing. It adds multi-monitor support, scripts that run during cycle changes, and custom dynamic wallpapers containing more than two images. Unix, AppleScript, and Automator scripts provide a way to connect wallpaper transitions with other macOS workflows.
Its main strength is a clear, narrow feature set built around automatic wallpaper rotation. Sunrise and sunset timing, custom sequences, live wallpaper behavior, and performance controls cover the essentials without extending into unrelated desktop features. Email and community support are listed, and the official App Store listing shows version 3.3 with a 2019 update. Choose Day & Night if you want lightweight macOS automation and the free feature set meets your needs, or if multi-monitor and scripting features justify the small Premium purchase. Choose an alternative if you need broader platform coverage or a wallpaper product centered on a larger content ecosystem.
