My above comment is not an excuse for design spam. The design spam rule is necessary. Your feedback is not.
Synths have never been a high profit business on iOS. And small earners are not a priority for Apple review. There’s a business case for not being bothered with most indie apps.
To suggest there’s categorically no room for innovation or value add with new synth products is just ignorant though.
It's like when the App Store started, someone made a Flashlight App and it was cool. We sure had enough of that by now. Now that AI turned everyone into a maker and the bar is lower in a world of abundance, it's only natural that things shift in terms of expectations for distribution.
This is how new markets take shape too, YouTube became so trash that now platforms such as Nebula came out as a business.
Is “we don’t think there’ll be a market for this” a defensible reason to disqualify an app from the App Store? What’s even your point? You are just looking to be argumentative and pretty clearly have no interest in actually discussing this.
technically, anyone can grab a copy of source, put their phone into developer mode and install the app too.
But- practically, it's hard.
You only get 4 application slots on devices in dev mode for example and I think they also expire.
I tried creating an internal app for my company and was gobsmacked that I didn't have any sane method to distribute it short of taking full ownership of everyones devices via MDM.
You are of course not allowed to publish "internal" apps to Testflight (or the App Store, but that's more obvious).
At least on Android you can make them self updating and not care about rest of the ecosystem
Second, to your point, say we trusted them, it's a chicken or the egg problem. After all the trash entered the space it became flagged and a scale/moderation issue.
The larger problem is the bad actors.
