While not equivalent to a true iOS app, PWA is a decent option that allows you to circumvent the app store restrictions. If you are trying to build apps primarily for yourself, it's a decent option.
Doesn’t that require you to host it and have it available on the open web, though? Is there a host that allows you to, for free, not only HTML/CSS/JS but also access to arbitrary tools and bespoke scripts on the backend?
Have PWAs stopped working on Android, or something?
I love PWAs. I just hope they never get too popular, or Google will kill them.
Actually I have been tinkering with PWA as a way to remake some of my toy apps. Though a lot of the automations I made for Android can be replicated through Apple’s Shortcuts app.
The biggest loss for me was Termux. I had lots of scripts and such that I ran, plus just having a Linux environment in my pocket was nice. Luckily I found ish which gives me alpine Linux on top of a virtual x86 machine as provided by a JITC layer. I can host PWA apps out of that environment for local use. Of course I can also ssh to my unix like machines from there too.
I am starting to tinker with swift a bit more too. As with google, I could buy a dev key to deploy my own apps only this way I have all the window dressing and end to end encryption on cloud storage.
