It’s nice hear the soothing melodies lying on the bed,it really calms your nerves but I would love to use it while working too. The catch is you need to pay for it. The app let’s you mix and play the music.like the birds with waterfall or anything you like. The advertising doesn’t disturb you much.nice melodies to choose from even in free section but only for sleeping!you have an option of timer which let’s you decide how long to play. I would give it a 3 star,if you like to relax with music you should go for it.
