Find calm, reduce stress, and take care of your mental health with heart coherence, guided breathing exercises, personalized mood tracking, and soothing soundscapes.

Heart Coherence:
Practice heart coherence with ease using 5-minute guided sessions. Track your heart rate in real time with pulse measurement before and after each session. Breathe at a rate of 5.5 seconds, the optimal frequency validated by science to balance your autonomic nervous system.
