Nacho Notch is a free Android app developed by Zachary Wander that helps to hide the unsightly notch on your phone's screen. The app colors the status bar black while your device is in portrait mode, making it blend in with the notch and thus "hiding" it.

The app is not limited to notch owners, as it can also be used to change the color of the status bar to black for a more uniform look. Nacho Notch dynamically finds the height of your status bar, so you won't have to deal with manual sizing.

It is important to note that the app works through a custom Quick Tile and not through the launcher icon. The app cannot be used on the lock screen as Android prevents screen overlays. After installing, ZenFone 5 users may have to reboot their device if the tile doesn't show up in the quick settings menu due to a ZenUI bug.

Overall, Nacho Notch is a useful app for anyone who wants to hide the notch on their phone or change the color of their status bar.
