Apps are always nice, but lots of mobile websites, including the kbin one, are entirely functional as an app. In your browser you can just make a shortcut to them, and they’ll appear on your home screen and act as an app.
In technical terms these are Progressive Web Apps, but it means you don’t need to wait for someone to write an app (or kbin to have a good API for doing so) to use it like an app on your phone.
In Firefox it looks like this. Open the website, in the menu hit Install, drag the icon to your desktop. When you click on it it’ll open the site like it’s a standalone app.
Chrome is exactly the same, but the menu button is “Install App” instead.
Doesn’t work well with Firefox mobile as the default browser on Android. I put the app on my home screen but if I switch to Firefox to look at some web page then go back to the “kbin” browser app it’s just a blank screen and I have to kill the window then reopen kbin.
Maybe it’s an OS issue? I’m using a Pixel 6a and haven’t experienced this.
