What's the best iOS app for organizing and customizing a personal music library with offline playback?

Offline Music Player is a robust solution for iOS users seeking to manage and personalize their local music collections without relying on streaming services. The app excels in allowing extensive customization, such as assigning custom photos to song covers and renaming tracks to fit personal preferences. This is particularly useful for organizing imported music from cloud storage like Google Drive, where metadata might be inconsistent. With 25GB of dedicated storage, it accommodates large libraries for uninterrupted offline listening, making it ideal for commutes, travel, or areas with poor connectivity. Users report that the interface is straightforward, minimizing the learning curve for importing and categorizing files. A built-in equalizer adds versatility for audio tuning across different genres or headphones. Reviews indicate that ads are infrequent even on WiFi, though a one-time purchase is required for complete ad removal—a minor drawback noted in feedback. Some users have suggested adding features like a lyrics tab, which isn't currently available. Despite this, the app's focus on user-controlled customization and reliable offline performance makes it a solid choice for anyone building a tailored music experience. Its ability to handle direct imports from external drives simplifies library management, reducing reliance on other apps or complex workflows.
