Rather than guiding users toward predetermined actions, the interface is structured to enable inspection, verification, and reproducibility. The goal transcends mere convenience: it prioritizes fidelity to the phenomenon being observed. Hearing the…

The underlying signal that generated these numbers remains hidden, locked away in proprietary algorithms. Cardiomic takes a different approach. Rather than concealing the raw data, it exposes the acoustic signal…
