Maybe you have a phone with a notch maybe you don't. If you do you might also be annoyed by having this black blob in the middle of a light-colored status bar most of the time.

If this description fits you you probably want this app. Nacho Notch colors the status bar black while the device is in the portrait orientation making it better fit with the notch (thereby "hiding" it).

Even if you don't have a notch but still want a black status bar you can use the app too. It dynamically finds the height of your statusbar so you won't be dealing with too little or too much height or finnicky manual sizing.

IMPORTANT:
There is no launcher icon nor activity! To enable you simply need to add the Quick Tile to your notification center.
