This is one of many reasons why I have a terminal on my phone, I can just apt install magic-wormhole and use it like on any other system.
(The technical reader will note that a terminal does not give you apt, but mentioning that I have Debian running on the phone is more confusing, as it sounds like I replaced Android (which I did not) or maybe that it costs a lot of battery (the tools are idle when not in use, unlike many apps unfortunately...).)
Sure, I can use wormhole on iSH on my iPhone/iPad if there are no alternatives. But there are alternatives, so I’ll definitely stay the hell away from it given the terrible ergonomics.
Maybe someone should write a magic-wormhole mobile client. It wouldn't need a complicated UI at all, and you could (try) to use Kivy[1] to avoid having to rewrite all of the Python bits. I might even try to do it as a weekend project, actually (though I suck at mobile development -- anyone else would probably be a better choice ;]).
