Darkr supports simplicity, concentration & privacy: this simple yet powerful background-app gives you a quick light/dark-switch in the menubar, a quick mic-mute, a mac-concentration-button - and lots of options to fully control the 'dark-mode' of your mac: add personal, automated daily light/dark-times (yours or through local sun / moon-position), switching-sounds, -hotkeys or just only darken/lighten the colors of your macs windows. You can increase your concentration by reducing distracting macOS-animations and eye-candy to a minimum. A 'privacy-option' lets you increase the boot- and sleep-security of your Mac. This little tool is ideal for power-users. It does not track you and is completely free (donationware).
