Instagram and Snapchat want to say hi.

Even stuff like TextPlus that lacks desktop clients. I can think of quite a few apps I'd immediately grab.

Maybe Venmo since there is no desktop/web client. It frustrates me that Venmo has become so popular in my circles when it’s smartphone-only. I have a smartphone so I’ll keep using it there, but I could imagine some might appreciate the option to run apps like Venmo on a PC.

There's a growing number of mobile apps that don't expose all their features through their web apps, e.g. Cash, Venmo, TikTok, Instagram, Snapchat etc.

It's a total pain for me to have to always open my phone and use the tiny keyboard to carry out some trivial task.

All the streaming services that allow you to download/save shows/movies for offline viewing, only offer that feature on their apps.

It's probably more interesting on things like Microsoft surface. Not sure Microsoft have the stomach for it yet, but they possibly could have another crack at doing phones.

Any app that has developers who think that making an Android version (TAM: 1B+ users) is more important than creating a native Windows version (also 1B+ users), is an app that I will want to run on Windows. I mean, I'd rather have a native Windows app, but if that's not an option, I'd rather have an Android app than a website in most cases.

Windows doesn't have a lot of great touch friendly apps since Windows 8 was a huge failure.

I could see myself using this if I ever bought a windows tablet.

For example, if you like comic books, the touch friendly comic readers on windows are pretty bad. Also the biggest comic store, Comixology from Amazon, is not available in a windows app version.

Lots of games, and some apps/services are mobile-first. I play a few different android games on my PC in an emulator. The best (IMO) Twitter client around is also Android-only.

Plenty of board games have android only apps that let you play multiplayer, but no web or windows app.

So that is one use case! They even tend to support tablet layouts.
