Some of the apps in the list are not an exact replacement of Duet Display, as they are more likely to mirror your computer display to iPad rather than using it as the second display. But nonetheless, they still do something out of the box, which is why they made into the list. Read: Best Youtube alternative apps for iPhone/iPad
Duet Display Alternatives
1. Sidecar (upcoming)
In WWDC 2019, Apple announces, Sidecar. The perfect replacement to Duet display. Just like Duet Display, Apple’s Sidecar works directly with a wired connection or wirelessly via Bluetooth. Unlike Duet Display, there is no WiFi support, which means, it will only work within a range of few meters. Also, both iPad and Mac should be under the same iCloud account. Once connected, you can use your iPad as a mirrored desktop or secondary display. Of course, it also supports Apple Pencil. However, most of you won’t be able to use this feature yet. You need to be running the latest software i.e. macOS 10.15 Catalina on your Mac and iPad OS on your iPad, both of them not yet released to the public. Although, you can try the public beta, which we did and unfortunately, the sidecar feature didn’t work for us as of yet. But Apple being Apple, once this feature rolls out officially, I’m sure it’s going to work flawlessly.
2. Easy Canvas: Draw on iPad for your computer
Artists all around the world have loved the idea of digitally drawing their ideas because with technology everything can be accentuated and becomes a little easier to follow through. Professional Graphic Tablets are pretty expensive on their own and it would be nice if we had a more viable option.
EasyCanvas is a mirroring app that lets you project your mac or windows computer on the iPad, pretty cool right? It is available as an app for the iPad and a software package for the computer. The computer applications are available for free and you can download it from the website. How does it work? EasyCanvas works as a digitizer and is very easy to install.

I’ve personally used Splashtop for a long time and they’ve grown as a company and rolled out a few different software. Splashtop Wired Xdisplay is specially designed to convert your iPad or any mobile device for that matter into an extended screen of your computer.
How it works? Splashtop Wired Xdisplay requires the installation of two separate software agents, one on the mobile device and the other on the computer. The desktop agent is a very simple app that works by creating a digital extended display on the desktop and then projecting it to the iPad. Rather than just projecting your extended display, you can also control the actions with the touchpad. There isn’t much left to do after that. You don’t get additional features like customized pencil strokes or palm rejection. Second Monitor: Yes, it is just a tool to convert your iPad into a second Screen.

5. Team Viewer: Free Alternative to Duet Display
Team Viewer is one of the biggest players when it comes to remote desktop services. It offers free services to consumers and a paid version for commercial use. It initially offered desktop to desktop remote access over the internet. Its services are highly dependent on the network speed and it works with an encrypted key to provide security. As the mobile devices became more powerful and fast, it only made sense that we had an option of using our mobile devices as hosts or guests to log in to remote devices. TeamViewer allows any device to access a device anywhere on the planet to be accessed, provided it has the TeamViewer Software installed and a working internet connection, preferably high speed.
How it works? Downloading the software is easy and done through their website. After installation is complete, the app displays a unique ID which is unique worldwide and you can access it only with the password generated right below. When you type the Id and password and hit enter, the app takes over the screen and starts transmitting it over the internet to the device that has accessed it. You can control the mouse and keyboards of the remote device with your own input devices. TeamViewer translates all the input values and sends them over to the remote destination. this app has one additional feature which transmits the audio from the remote destination to your device. For example, if you were to play a youtube video through TeamViewer on the remote device the video will play with audio on your device as well, this feature isn’t available with the other apps. Second Monitor: There is no option to use your iPad as a secondary display using a TeamViewer app, however, you can still control your Computer from your iPad.

Now when everything is ready, the mac window displays the connected device as an icon. You just have to click connect and just like that, it makes it an extended display.

To fuel our productivity, the apps listed in this list are versatile. EasyCanvas and AstroPad act as a mirror and a digitizer with a special apple pencil touch feature. It lets you make the best use of creation tools. If you’re looking for something more than just a digitizer, Splashtop takes the cake. It has options to make it an extended display too.
