Beyond Simple Breathing — Designed for Gradual Training This app goes beyond basic breathing guidance. It is designed to help you gradually improve your breathing capacity. You’ll begin with shorter breathing cycles, and as your training progresses, the durations increase automatically, guiding you toward deeper states of meditation. If you prefer fixed patterns, you can customize the breathing rhythm to suit your needs. Breathing with Music Throughout your meditation, the calm and elegant music of Johann Sebastian Bach accompanies your breath. The harmony between sound and breath leads you toward deeper inner peace. A Background for Immersion Personalize your meditation space by choosing your favorite quote or image as the background. This visual stability enhances focus and deepens your immersive experience.
