I
Sense
Heart rate, HRV, and motion — passively — from Apple Watch. Over the first week, HeartCore learns your personal physiological baseline. Not a population average. Yours.
The system
Four operations, one continuous loop.
HeartCore runs quietly underneath your day. No habits to learn. No data to interpret. The only moment it asks for your attention is a tap at the wrist — and even that asks for one second, not a feature interaction.
II
Detect
When you enter Prep or Live mode, the system watches for meaningful deviations. Trajectory, rate-of-change, multi-signal agreement. Patterns relative to you — not raw thresholds.
III
Cue
When the state breach is confident and the context is real, a single discreet haptic on the wrist. No screens. No copy. A reminder to breathe, slow, and re-access clarity.
IV
Reflect
After the moment, a brief reflection: outcome, state, recovery. Over weeks, the system surfaces your activation patterns and recovery signatures.
HeartCore evaluates deviation from your rolling personal baseline, requires multi-signal agreement, and degrades gracefully when signals drop out. HRV is the primary signal when available; heart rate and motion carry the system when it isn't.
