Three sensors, explained in plain English

Biofeedback shows you what your body is doing right now, so you can practice changing it on purpose. It's a training tool, not a medical test. It doesn't diagnose anything, and your numbers are there to practice with, not to judge you.

• Heart (HeartMath Inner Balance): your heart doesn't beat like a metronome. The small changes between beats are called heart rate variability (HRV). When you breathe slowly and evenly, that rhythm tends to smooth into a steady wave, a pattern HeartMath calls coherence. The sensor shows it live.
• Breath (Airofit): a breathing trainer that adds adjustable resistance as you breathe in and out, like weights for your breathing muscles. The app tracks your breathing strength and capacity, and short drills train slow, controlled breathing you can use under pressure.
• Brain (Muse EEG headband): sensors on your forehead and behind your ears read your brain's electrical activity and turn it into sound, with calm weather when your mind settles and rising wind when it wanders. You hear the drift, you come back, and that return is the rep.
