Undisturbed is a small and really clever menubar app by Arno Appenzeller that lets you focus on your work more effectively. It works by enabling the Do Not Disturb (DND) mode on your Mac and disabling the Notification Badges in the Dock.
The Do No Disturb (DND) setting on macOS disables all notifications and alerts, but you still continue to see app icon badges for all apps in your Dock. This works in most cases, but if you really don’t want to be disturbed, then Undisturbed is what you should be using. It enables the DND mode and also disables the red notification badges, so you can fully concentrate on the task at hand.
The app is Free to download and use as long as you want. There’s an optional Pro mode, which can be unlocked via a $3.99 In-App Purchase in the app, that unlocks features like an ‘Alt-Click’ option to enable Undisturbed, a ‘Launch on Startup’ option, and ‘Unobstructive notification indicator in menubar’.
