If you’re a developer you can kind of do it, or so ChatGPT tells me:
> So for, say, your iPad mini plus 2–5 other iPads, the workable setup is: Mac + Xcode → $99/year developer membership → register each iPad's UDID → create an Ad Hoc build → install that build on those devices. You don't have to publish it, make it discoverable, or have Apple review it.
That would work for me, except that I prefer to build web apps instead. There’s nothing I really want to build that couldn’t be done as a web app.
As for why one computing platform would be different than another, if you don’t think there’s any difference then why not use a Raspberry Pi or something?
The $99/yr part gives me the ick.
> $99/year developer membership
Yeah...
> then why not use a Raspberry Pi or something?
Because a Raspberry Pi would be very inconvenient to use as a smartphone, obviously. Doesn't explain why it makes sense to treat one ARM computer as a mildly locked jail (Macs) and another as a hard locked jail (iPhones and other handhelds); I feel like the only explanation here is that the smartphone duopoly has worked hard to condition customers into accepting this.
