I desperately want active breath monitoring. Like measuring breaths per minute. Like nudging me when I'm holding my breath.
These features would greatly help me with managing chronic pain.
Also, the "pulmonauts" are doing a bunch of cool new stuff. Active breath monitoring would be a boon.

Out of curiosity, I tried using some decibel meter type apps to detect my breathing (breath sounds). Just to see if it's even possible.
I didn't get very far. I haven't had the gumption to investigate further. Use an actual mic and tape recorder, because maybe the iPhone is doing active noise cancelation or something. If there's actually some signal (sound), maybe there's also a way to get the raw data from the iPhone mic.
Asked another way, I'm not smart enough to figure out if an iPhone's stock mics are sensitive enough to pick up 10 decibels (breath sounds). My google-fu is weak.
