MrLittleKing ,

Amazing app !

I normally don’t bother writing reviews for any products I use. But this definitely deserves one.

I am currently teaching virtually to a group of students. It’s my first time doing so. I needed a second monitor, one I can use for teaching virtually. I tried using Duet. It wouldn’t work, no matter how much I tried. I paid for the app and membership, still wouldn’t work. I gave up trying.

I was suggested to try this app. I was cautious, since I didn’t hear anything about it.

After using it for an entire month, it’s definitely the best app I have come across. I am surprised it’s for free! The app is amazing. I really can’t think anything negative about it. I do wish there was a way to connect to iPad using a wire instead of the network connection. Other than that, I can’t complain about anything else.

Thanks again for making this app. It was a game changer for me at work.

Thank you very much for your detailed feedback :)

So much better than Duet

I moved from Duet because their software broke my computer. I had to restore it because Duet disabled my dedicated GPU and it wouldn’t work even after the app was uninstalled.

SpaceDesk is less intrusive, free, doesn’t require an account, and works better than Duet. The only issue with this app is that you lose connectivity when you trigger the Notification Center or when you receive a call (if you have hand off enabled). Minor issues that can be fixed via a software update.

In the time being I highly recommend SpaceDesk.
