Well worth it! Ive purchased several similar apps prior to finding this one and have deleted them all. Its the only calming noise app I need. Not only do I use it when Im having trouble getting to sleep or back to sleep but my kids use it as well. When my oldest is having trouble staying focused on homework, when my 4 year old is taking an afternoon "break" or "quiet time" (shes just too big for naps) and even when my youngest (2) is in time out. 100% satisfied!
