According to ChainCatcher, developers of several iOS music apps say their submissions have recently spent weeks in Apple’s App Review process, despite Apple’s guidelines stating that at least 50% of submissions are reviewed within 24 hours and 90% within 48 hours. AudioThing’s Materia took 25 days to receive approval after one rejection, while Seconds, a collaboration with Hainbach, has been under review for 29 days. Pittsburgh Modular’s Microvolt 3901 synthesizer VST version was released on October 27, while its iOS version was delayed until November 12.
Michael Hetrick, a developer at Unfiltered Audio, said Sinusoidal Run Rhythm was rejected four times. Reasons included a request for a demo video, a request to verify licensing for the audio technology term “Polyharmonic,” and a determination that SRR MIDI was spam similar to SRR. After more than a month of correspondence, only the audio version has been released; the MIDI version is not yet available. Marek Dendes, developer of CRUX Synth, also said the app was rejected four times for reasons including “design spam” and duplicating existing apps. He said multiple appeals have received no response.
