The program imitated the iPod Classic interface: the menu, the cover of the track being played, and the scroll wheel. During the work of the latter, a vibration motor was even involved, creating a feeling close to the iconic Classic Wheel.
The app appeared on the App Store in October but has been viral on TikTok several times since early December. After that, Retro Pod disappeared from the App Store. Neither Apple nor the program developer commented on the situation, although it is evident that the removal is due to copying the interface.
A few years ago, a similar situation occurred with the Rewound application, which also emulated the iPod interface. Amazingly, such programs pass the App Store moderation at all although it can get worse!
