I realize the use case is small, but it would be nice.
Understood! But it’s a lot more work than it sounds — on an ongoing basis, because it means testing each new release on Vision Pro (and I don’t even have one) — and I’d rather spend the time improving the app instead of bringing it to new platforms.
(People also ask about Apple Watch, Linux, Android, Windows — or even just releasing it on the Mac App Store — and my answer is the same. I realize that running it as an iPad app on Vision Pro is less work than an Android port, for instance, but it’s still a lot more work than just checking a box and forgetting about it.)
Perhaps TestFlight only, at least initially.
