Very interesting concept and neat visuals. Before I dive in, I'm a trained vocalist and breathing is core concept #1. My feedback may be geared towards our line of work, but I believe breathing mastery is analogous across domains. Here are my initial thoughts:
Using the microphone and camera makes sense. When the camera required calibration, my excitement grew. Then my anticipation gave way to disappointment when the bar had no sensitivity to silent breathing, nor 'shoulder breathing.' I'm now struggling to know what the camera is needed for - ideally you want to see if someone is shrugging their shoulders instead of filling their diaphragm, but the camera positioning isn't suited for that - nor did my experimentation reveal the app's sensitivity to that input.
Further, while one can 'cancel out' the audio stimulus from the audio input in software, I wonder if there's interference. I found it takes a significantly 'loud' breathing to get the bar to move along with me - and even still, the bar shifts before I'm ready to shift. In some sense, I guess that's the intended behavior change - however, not all loud breathing is good breathing and leaving us without feedback that we should change our breath tempo doesn't help us get better.
This overall is a wonderful idea - and would be perfectly fine (really better in my opinion) without the request for camera and microphone access.
