What is a notch app?
A notch app is a Mac utility that turns the area around the MacBook notch into a small panel of tools. You hover or click the notch, the panel opens, and it shows things like music controls, a clipboard list or a timer.
Why it matters
The notch is in the same place on every screen and always in view, so a panel there is quick to reach. The menu bar has little spare room, and a panel gives each tool space to show more than an icon can.
What it cannot do
The panel is drawn by the app on top of the screen. It does not change the camera hardware, and it does not add room to the menu bar. Some notch apps also copy the iPhone idea of a Dynamic Island.
How NotchStar fits
NotchStar is a notch app with ten tools: Home with Now Playing, Shelf, Clipboard, Calendar and Reminders, Quick Notes, Timers, Teleprompter, Mirror, System and Disk. It needs macOS 14 or later and costs $4 once. Prices as of 4 November 2026. On a Mac without a notch it draws a small floating pill instead.
