Apple App Review — AI-made apps slow down music developers
In short

Vibe-coded apps are flooding the iOS music category, and established developers say App Review is stuck.
What is it?
Synth Anatomy's report says an estimated 10–20 new iOS music apps reach the App Store every day, because AI lets anyone vibe code apps and AUv3 plugins. Apple's own guideline is to review at least 50% of submissions in under 24 hours and 90% in under 48 hours.
How does it work?
Established audio developers describe long waits and odd rejections. AudioThing's Materia took 25 days and one rejection, its Seconds app with Hainbach had been in review for 29 days, and Pittsburgh Modular's Microvolt 3901 reached iOS weeks after its October 27 plugin launch. Unfiltered Audio was rejected four times, and Michael Hetrick wrote that "Apple seems to be using AI for automated App Store reviews"; CRUX Synth was rejected four times for "design spam".
Why does it matter?
The story shows a knock-on cost of cheap AI-built software: review queues and spam filters fill up, and small professional developers pay for it with delayed launches. The author asks Apple to re-engage directly with iOS music developers.
