Sararak

Sararak

Sounds for focus and rest

Rainfall, forest ambience, ocean waves, a crackling fire, the buzz of a busy cafe. Pick up to four sounds and make your own background mix. Set the volume of each one and let your mix loop seamlessly.

Coming soon to the App Store and Google Play

When to play it

Like white noise, it is sound to keep on in the background. When a room feels too quiet, fill it with the sounds you want to hear.

Foldables and iPhone Duo

On foldables and iPhone Duo, Sararak splits the screen along the fold, so no buttons or text land on the crease.

iPhone Duo

  • Unfold it, and the sounds sit to the left of the fold with the mixer on the right.
  • Turn it upright while unfolded, and the sounds sit above the fold with the mixer below.
  • Fold it, and it looks just as it does on any other iPhone.

Android foldables

  • Unfold it to see the sounds and the mixer side by side.
  • Half-fold it and stand it on a table (tabletop posture), and the sounds sit above the fold with the mixer below.

Playback keeps going when you fold, unfold, or rotate the device.
