    Favorites and offline listening

    Favorites. Tap the heart on any player screen. Favorited tracks collect on your profile so you can get back to them without searching.

    Downloads. Tap the download icon on a player screen to save the audio to your device. Downloaded tracks play with no connection at all, which matters on flights, in basements, and anywhere with weak signal.

    Find everything you have saved under Settings, in the downloads section.

    Remember that frequencies never need downloading. Every tone in the Generator, the Solfeggio tab, the Infinity tab, and the Frequency Library is generated on your device in real time and works offline by default.
