Almost perfect, just a few details missing
This app is almost perfect. It allows to fully personalize the breathing cycles and display/visualization during exercise is exactly what I want. Just a few details are missing - a timer to set session duration - a sound guiding feature to allow for sessions with closed eyes (e.g gongs and/or light bliss during breath-in / breath-out) - possibility to save breathing exercises setting (box breathing, cardiac coherence, etc.)
