Full album of relaxing music included with the free version. Improve your relaxation and get more refreshing sleep.

The Sonosync app contains five different musical compositions, each recorded at three different tempos, providing over two hours of music. Our studies have shown that listeners find the version with the tempo closest to their heartbeat to be the most relaxing.

The free version of this app allows you to listen to five full length compositions at the highest tempo. All the music has been mastered for iPhone and iPad listening. We recommend headphones for the best quality, but the mixes have also been optimised for the built-in speakers.

Unlock the extra features and receive the following:

Full control

Get all three variations of each composition. You choose the tempo that is most relaxing for you. Over time you may find you gradually move to the slower versions as your relaxation levels increase.

Each variation was recorded and mixed separately by the composer. There are subtle differences in every recording, in order to make the music work perfectly at each tempo. Every note, beat and echo is in perfect sync!

Drift into sleep

Use the sleep timer to automatically fade out the music and drift into a peaceful sleep.

Get all the photos

You will also receive all 36 beautiful photos which automatically play in the background.
