I know so many issues and bad things on the computer. You only can use it on the browser. And not all the features are working there. Things like chatting with others. I hope that there will be an app on the PC too. But otherwise you can use an android emulator like blue stacks to use the app. I think that it would be better to use the phone instead of blue stacks. It's way better than that.
Well it's not really installing the phone app on a desktop environment, but I have been using the Samsung Dex to use my phone apps on my PC.
And it only works with Android phones, unfortunately!
But it has been a life changer for me!
