The App for nocturnal people 🦉

Easily toggle macos Mojaves dark mode

Time based

NightOwl will toggle the Dark/Light Modes based on your chosen time. You only have to set it up once, then it will run in the background.

Sun based

Want your Mac to be in Dark Mode during night and switched back to Light Mode, when the sun rises? NightOwl does the work for you.


It only takes you a second to switch between Mojaves Dark/Light Modes by using the Hotkeys. Press, "Huuhuuhhh", dark. - that easy

Why I developed NightOwl

Early on I installed the beta version of macOS Mojave on my MacBook, because I was looking forward to the dark mode. During testing I immediately noticed that every time I switch between dark and light design, I have to navigate to the settings with a lot of effort. At some point I thought:

"This has to be easier, a simpler solution has to be found".

The idea for NightOwl was born. At first I started to develop a simple menu bar app that allowed me to switch between the two modes. Since the small tool brought me a lot of added value, I thought that other users could also benefit from my app. I designed a suitable app icon and made the first version of NightOwl available for download.
