It would depend on your definition of porn of course, but at least in Germany you can get pornographic magazines at lots of kiosks/stores, especially the bigger ones
> So exactly what would a Pornhub app do that you can’t do from the website?
Well, we don't know. But porn has historically been at the forefront of digital technology, so maybe some investment in sectors like AR and VR is being held back by the fact that Apple would never allow porn-related apps.
We should know because Android is much more open and they would have the opportunity to create their dream app. Where are the great porn apps for Android?
It's well-known that the real money in apps is in iOS, which dominates the top-end of the market. The AppStore makes much more profit than the Play Store despite being on 1 device for every 4 Android ones. In that situation, if you have no access to the most lucrative audience, it makes sense not to invest into apps at all.
It's also not trivial to install Android apps outside the Play Store, for non-geeks.
We are talking about porn. Do you know the lengths that people will go to see it? That would be a killer app. Heck Pornhub could sell a custom Android device just for that one killer product. Anyone who has a modicum of capital can get a run of customized AOSP based devices to resell.
