FAQ
Frequently asked questions.
A smartwatch measures at the wrist, which is enough to track an average heart rate. Our sensor measures at the earlobe, where the signal is most stable — which is what makes precise heart rate variability possible, the key metric for coherence.
The sensor reads your signal directly at the ear, where it's clearest. The resulting heart rate variability is precise and faithful — perfectly suited to your day-to-day coherence practice.
