Measure your breath, your heart,
your inner resilience.
A clinical-grade breath-hold and pulse assessment, guided in real time. No equipment. Two minutes. Insights from twenty years of respiratory and cardiovascular medicine.
How the test works
01
Measure pulse
Tap with your wrist pulse for 15 seconds. We calculate your resting heart rate.
02
Inhale deeply
Four seconds of guided diaphragmatic inhalation, then hold the breath.
03
Hold & learn
As the timer rises, watch live physiological insights at each stage. Release when ready.
Safety: Sit down. Do not perform this in water, while driving, or while operating machinery. Stop immediately if you feel lightheaded. This is an educational wellness tool, not a medical diagnosis. People with heart, lung, or blood-pressure conditions should consult their physician first.
This assessment is an educational wellness tool inspired by clinical breath-hold (apnea tolerance) and pulse-palpation methods used in cardiopulmonary screening. It is not a diagnostic instrument and does not replace medical advice. If you experience chronic shortness of breath, chest pain, palpitations, or dizziness, consult a qualified physician.
