How can it be made available on iOS? I use it on desktop browser, but I also have Plebstr Web App on my phone and I'm honestly not sure how i did it at this point. I don't see an easy option on their website, but the app store version doesn't see itself on my phone so I'm pretty certain its a web app.

I'm not sure about plebstr, but after you've used coracle a few times, a "install" button should show up in the menu which will allow you to install it as an app.
