The word Lungy grosses me out. Something visceral. I imagine viewing a human organ or the chest being opened. Sorry, but I thought it might help you. If people agree, say something below. If not, I am an oddity and can be ignored.
The anatomical term "pia" can be pronounced as if it starts with either "pea" or "pie". Writing "pi-a" is very strongly suggestive of a pronunciation like the Greek letter pi (i.e., like "pie", not "pea"), especially as the website's favicon is the letter pi. However, the website says it's pronounced "pea-uh".
So I would think that the hyphen would bias people towards the "wrong" pronunciation.
More breathy and airy than organ-y and meaty. Probably already 900 apps called "Breathe" though
It also makes me think of lunge exercises.
It also seems like an expensive domain name to buy.
