Zenteek

Requires the macOS app “Zenteek” to function. This iPhone app acts as a companion and has no standalone functionality.

It allows you to take your personal music library with you. Transfer your playlists, awesome mixtapes, and favorite albums directly from your Mac to your iPhone over your local network connection with a single click. Once downloaded, everything plays offline, fully independent of any internet connection. Control playback with the classic iPod-style wheel interface. Your playback activity is synced back to your Mac whenever you reconnect, contributing to your desktop insights. You can either transfer the original file formats or choose to have Zenteek automatically re-encode to AAC to save storage space and time.
