After i updated my 5s to iOS 10 audio hasnt been playing.
I tried turning my phone off and on again but nothing changed. Hope this issue gets fixed soon.
Other than that its a good app and helps motivate me to actually sit and do deep abdominal breathing.
One issue is i cant go back to my old breathing sessions and look at the graph of how i was breathing. And when i do it with my current session the line goes red.
mindtl about BellyBio Interactive Breathing, v1.1.3
