How Steady reads stress
Steady is built on heart rate variability (HRV) — the natural variation in time between heartbeats. Higher variability usually means recovery and calm; lower variability signals strain.
The Steady companion app for Apple Watch measures HRV quietly in the background — no check-ins required.
Everyone's HRV is different. Steady learns your personal range, so "elevated" means elevated for you — not a generic average.
Your day is sorted into three simple states over 24, 48 or 72 hours — with insights on the stressors behind them.
Simple pricing. No pressure.

Heart rate variability is the tiny variation in time between heartbeats. It reflects how your nervous system balances stress and recovery — a well-studied signal of how you're really doing.
Your data stays yours. Steady reads HRV through Apple Health with your permission, and your measurements are never sold or shared.
No. Steady is a wellness tool for understanding everyday stress patterns. It doesn't diagnose or treat any condition.
