Screencasting is no longer a new thing. But it's no surprise to see some folks ask, "What is screencasting?" when a friend or colleague asks them to screencast their device screen.

With that said, worry less if you fall into the same category of folks. You're just a few paragraphs away from learning about screencast technology.

In this post, we've discussed all you need to know about screencasting. From what it is to how it works, apps that can be used for screencasting, and lots more. So, without wasting much time, let's dive into the article to get cracking!

what is screencasting?

Part 1. What Is Screencasting? Is Screencasting Safe?

Screencasting involves casting content from a smaller screen to a larger screen. It allows you to cast content to another display and still use your device without showing off its on-screen activities or interrupting what is being cast.

For example, if you cast a video from your phone to a TV, you'll be able to see the video on your TV only, thus allowing you to perform other activities on your phone while screencasting the video.

Ultimately, there's no risk in screencasting. Instead, it's the best way to effortlessly see content on a small screen with a large screen. You just need to ensure you're using a trusted tool to execute a screencasting operation.

Part 2. What Is The Difference Between Screen Casting And Mirroring?

There's not much difference between screencasting and screen mirroring. Both techniques are a way of projecting content from one screen to another.

However, screen mirroring allows you to mirror the activities on your small screen to a bigger screen in real-time. At the same time, screencasting casts the content from one screen to another displaying your device screen activities in real time.

Description It involves projecting content, like a movie, youtube videos, etc., from a small to a large screen. Whatever you do on your small screen won't be displayed on the large screen in real-time. It involves mirroring your whole device screen to a PC or TV.

Screen View Different contents are displayed on two screens at the same time. The same content shows on two screens simultaneously.
Content Only specific content is displayed, for example, gameplay, YouTube videos, movie, etc. All on-screen activities, calls, chats, videos, etc., are displayed.
Internet It usually uses home WiFi, though it can sometimes be executed via built-in WiFi. No internet connection is needed. Instead, connection is established via built-in WiFi.
Multitasking Yes, different things can be displayed on the two screens simultaneously. No, the same content is displayed on both screens.
Screen Time-out Receiving device's screen still displays content even if the sending device screen is blacked out. Yes, if the screen of sending device is blacked out, the receiving device will do the same.

Google Home App is a virtual assistant developed by the Google Tech team to facilitate various operations, including free screencasting to allow you to reflect your smartphone to a big screen.

Rating: 4.5/5

User Review: "Google Home is a great app. It brings all my automation devices together for easy use. The one improvement that is most lacking is the ability to place multiple devices into subgroups within a room. For instance, I have two light bulbs in a fan, and it would be helpful to put them in a group with a single name. As it is, I have to give them names that go together, like 'Rice and Beans."

2. AirDroid Cast

AirDroid Cast is another powerhouse for performing screencast operations. But, unlike Google Home App, which only allows you to cast a phone screen, this app allows you to efficiently cast a phone or computer screen to a PC or any device or browser.

The tool is supported on all platforms, including Android, iOS, Windows, and Mac. Plus, it offers various means of executing screencast operations via USB, WLAN, or AirPlay. Overall, AirDroid Cast does not disappoint. So, it's worth trying.


  • It's easy to operate.
  • Secured encryption.
  • Smooth connection process.
  • Simple and intuitive UI.


  • Some features are closed behind paywalls.

Rating: 4.3/5

Review: "I've needed this forever. I only have hotspot WIFI, so I've always connected my phone to my TV with an HDMI adaptor to watch streaming channels. It's effective, but having to lean over and peck at my phone to control what's on TV was irritating. Now I can use my mouse! I CAN "link to Windows", but that presumes that I have any hotspot data left. You have to buy premium for USB casting, but at $29.99 per YEAR, it's not a problem at all."

3. Roku App

Last but not least is the Roku Mobile app. Although Roku is a streaming app, it can also be used for screencasting, which is great for screencasting your favorite movies on a big screen.

The Roku app is available on Android, iOS, and Windows devices, and it's easy to use. So, even if you don't have a technical background, you can still use it to execute a seamless screencasting operation.


  • It's easy to operate and affordable.
  • Supports many streaming apps.
  • The mobile app can come in handy as a remote control.


  • There have been complaints from users about frequent lagging.
  • The only means of establishing a connection between devices is WiFi.
  • Poor WiFi antenna.

Rating: 4.7/5

User Review: "It works. But with the most recent update, I don't think I have access to changing the picture settings of my TV while watching my show like I used to. I have no access to turning my picture off. Other than that, my only complaint is how often I need to close the app and reopen it to use the remote after a while. And the fact that sometimes it just won't connect to my TV."


Years back, no one ever thought it would have been possible to cast a device screen to another just within a few clicks. But all thanks to tech experts for coming through with such innovation to alleviate how we watch things on a small screen.

We believe the above article has clarified what screencasting is. So, at this point, you should be able to tell the difference between screencasting and screen mirroring and know how to screencast your phone or computer screen without hassles.

Nevertheless, if you need to screen mirror your device, you can use the Dr.Fone Air - Online Screen Mirror App for the operation. It does the job smoothly.
