Croma lets you play the music inside your local media library (Built-in Music app), and it has a very simple and elegant interface.

Besides rating, searching and filtering, Croma provides you more functions such as looking for music with similar title within your music library, accessing and update the metadata such as skip count, play count and last played. Croma also allows you to copy or save artworks of the music.

In addition, Croma gives you the ability to set a timer to stop playing automatically after a specific amount of time. If you want, Croma can also enter full screen mode to keep the screen on and display information of the music when it is playing.

Moreover, with Croma you may customize home actions as shortcuts where 3D Touch is available. With those shortcuts, you can play music, set playing mode and set a stop timer with only one press on the home screen.

Because Croma plays the music inside your local library, installation of the Music.app is required (available via the App Store). For how to add music to your device library, please refer to support.apple.com/HT201593.
