Native screen capture, one of the hottest features that Apple has integrated with iOS 11, is easy to launch from the optional Control Panel on your iPhone. From there, you can stop recording at the same location or via the red status bar. It's a very handy addition to iOS, but there's one obvious drawback – this red status bar that may appear in your shots.
When a screen capture is in progress (audio can even be activated!), The iPhone X will have a red bubble around the time in the status bar, while all other iPhone models will make the whole status bar at the top red. Anyway, taking screenshots can be quite annoying, especially if you do it for professional reasons.
The annoying red bar or blister that appears while a screen capture is in progress may be blocked by certain apps, such as Screen games, some photo editors, and others where the developer wanted to completely hide the status bar by default.
If you're in one of the apps that hides the status bar, Apple's native screen recording feature in the Control Center is a godsend. However, if you record the screen of your iPhone in an app that does not, you can also use other options so that the unattractive red bar or blister never appears.
Option 1: Use QuickTime on Your Mac
The best thing about the iOS 11 native screen capture feature is that you do not need to be connected to cables, but for high-quality recordings without red bars or bubbles it is necessary Unless you're recording an app that hides the status bar
If you own a Mac, you can record your iPhone's screen using the built-in QuickTime Player, if you're using macOS 10.10 or later and QuickTime Player version 10.4 or later. You also need a Lightning cable, so this does not work on older iPhones with the 30-pin plugs.
It's a pretty straightforward process, and we've already discussed it in detail, so I'm not going to do it over there. But you know that you can record both video and audio that way, and for the latter, it could be either the audio on the iPhone itself or the microphone on your Mac if you want to make a voiceover.
Option 2: Third Party Mac Apps  Because your Mac has an integrated way to communicate with your iPhone, such as the QuickTime option, other developers can use this system for their own apps. One of my favorites is Screenflow from Telestream. It's a bit expensive, but the editing options given to you are reason enough to justify the cost.
Other third-party applications available, most of those I have not personally tested, include Screen Record Pro by Xiaolei Zhang (9, 99 $) only for Mac, Animatrice from Telethon KK (free) only for Mac, which steals QuickTime recordings straight and not very well, LonelyScreen ($ 14.95 / year) for Mac and Windows and Reflector ($ 14.99) for Mac and Windows, just to name a few.
The only disadvantage of these apps (besides the price) is that the time in the iPhone screen capture will always be 9:41 and not the actual time, just like with QuickTime. However, this only applies to the apps that you need to connect using Lightning cables, not those that connect the screen wirelessly to your Mac.
Prior to Apple's native iOS 11 video recorder, there were a handful of iOS apps that you had to sideload to use, such as AirShou, EveryCord, Vidih and VizoRec. They did not make the cut, because in most cases either a red bar is still displayed at the top of the screen or the status bar turns blue instead. The apps are not very reliable and you do not even work in iOS 11.
There are now also some iOS apps in the iOS App Store that use the native Apple screen recorder to "stream" these videos to a service like Twitch. These include Anthony Agatiello's EveryCord (free) and Mobcrush (free), to name a few, but they fall victim to the same annoying red bar or blister you want to avoid using the native screen recorder.  There are also many jailbreak apps on Cydia, such as DisplayRecorder and CCRecord, but most of these improvements have not been updated to iOS 11, mainly because the official version of Cydia has not even been released for iOS 11. The development has slowed down overall.
