Honestly...

Considering that you have to pay for this, I think it should be updated. Confusing at first to use. And, unlocking each sound is time consuming and unnecessary. I do like the sounds and the app. now that Ive figured out how to use it. Sometimes music comes on the same time as Zen and I have not figured out how to turn that off. Great idea, nice sounds, should be a little simpler for ppl to use.
