Two devices.
One continuous loop.

Zen learns your daily physiology. Axiom adds clinical-grade cardiac signal. Together they feed the Alyna engine — for interpretation that knows you, not averages.

Two signals. One verdict.

Anomalies on Axiom are cross-confirmed against Zen physiology before any escalation. That cross-check is what makes Alyna trustworthy.

Cross-confirmation

Axiom anomaly + Zen context = verified event.

Personalized baseline

Both devices feed Alyna's per-individual envelope.

Network-tolerant

Local buffering on both — no signal lost.

One identity

One record, one app, one journey across all stages.

Procure the hardware. Activate the journey.
