So nobody in this discussion (nor the site) explains what "notch" means, in context.<p>---<p>It's a black box on the top part of the screen that houses the front-facing camera and other sensors. The notch easily distinguishes the iPhone X from its older cousins and is considered part of the overall good design.<p><a href="https://miro.medium.com/max/1000/1*2vE1g5s1yx-W3XNy9qjPGQ.jpeg" rel="nofollow">https://miro.medium.com/max/1000/1*2vE1g5s1yx-W3XNy9qjPGQ.jp...</a>
---<p>I assume this "app" adds hanging lights to the notch at the "top" of your device.
