Euphoria
I downloaded this app having heard of many things about yoga breathing excercises. I tried it once, following the diagramn and instructions and got a euphoric rush. My thoughts slowed down, and it was like I entered a deep meditation. Breathing is profound! I do not know if this has such an effect on everyone... but if it does, this app is well worth your time. After one trial, I decided that that five dollars was worth the full version-- this version being free, I highly recommend it to anyone.
