I just updated this app and tried to play it. So far it has crashed about 7-8 times. Not my idea of a peaceful experience.
I also think the sounds are too "technical" in that the way the engineers mic-ed the recordings, I can practically hear every water molecule as they ricochet off of the rocks. What about stepping back for a more rounded, mellow sound?
Im looking forward to further updates since few alternatives are available.
