Cool idea, needs work

Didn’t work well with my iPhone SE (timing of the music seemed off, maybe due to accelerometer?) Now with my iPhone 8 it works better, but there are glitches in the music (sounds like a CD skipping....?!) that are wayyy too distracting to ignore.
Wish this app was more like BellyBio, with the log of past sessions, different music choices, etc. Such a good idea, just needs some tweaks and it would be five star for sure.

Developer Response

Thanks for your feedback. We haven't been able to notice your issues on iPhone SE nor 8 but we'll try again... We're working on a major overhaul in the coming months. Regards - BellyBio Team


An improvement over bio belly

I like this better than bio belly since you can chose no music as an option and has a timer. Simpler but I did not need the other options.


For Females too ??

males breathing is abdimothoracic type and in females thoracoabdominal, so is it same for both, couldn't figure that out
