Flameinmind collects real-time informations on brain and heart activity (Brain data through Muse headband sensors and heart data through Polar chest strap sensor). This app is making a link between body waves coherence and sacred geometry: searching for Phi and octave rations in your Brain waves and heart rate spectra (as Bliss states are closely linked to octave and phi rations in the body waves). Flameinmind also includes binaural sound waves related to sacred geometry (Phi ratios) that can help to achieve bliss state in your body waves. Now version 4.0 including an update allowing to use the latest Muse sensors.
