I
Sense
Heart rate, HRV, motion — passively, from the watch.
Closed pilot · Apple Watch + iPhone
Protect access to optimal judgment under pressure.
A decision-state companion for the moments that count.
01 · Positioning
For the moments where judgment is the product.
We didn't build another wellness tracker. We built the system we wished existed for the actual minutes that move careers, companies, and decisions.
What it is
- A decision-state system for consequential moments
- Apple Watch + iPhone, working as one synchronized companion
- Real-time, personal, baseline-aware
- Privacy-first and on-device by default
What it isn't
- Not a wellness app
- Not a therapy or clinical tool
- Not a passive health dashboard
- Not a generic stress tracker
02 · The loop
Four operations, one continuous loop.
HeartCore runs quietly underneath your day. The only moment it asks for your attention is a tap at the wrist — and even that asks for a second, not a feature interaction.
II
Detect
Deviations from your personal baseline — not raw thresholds.
III
Cue
A single discreet haptic when state and context align.
IV
Reflect
After the moment, a brief reflection. Patterns surface over weeks.
03 · For whom
For people who pay a real price when judgment slips.
01
Founders
Where the next decision compounds for years.
02
Executives
Where composure is the deliverable.
03
Investors
Where pattern recognition meets pressure.
04
Negotiators
Where listening outperforms speaking.
05
Consultants
Where the room's read is the work.
06
Performers
Where the same nervous system shows up every set.
HeartCore is not built for general wellness, athletic training, or clinical populations. It is built for adults whose work depends on accessing their best judgment when it matters most.
04 · The science
Built on forty-two peer-reviewed sources.
HeartCore's detection model draws on the established literature on heart rate variability, prefrontal regulation, just-in-time adaptive interventions, and decision-making under acute stress. We aren't inventing a physiology. We're translating thirty years of it into a wearable form that fits an executive's day.

05 · Privacy
Privacy is a posture, not a footer link.
The whole point of HeartCore is that you can trust it during the moments that matter. Trust is what we don't collect, where it doesn't go, and how easy it is to walk away.

Your data lives on your device
Biometric and reflection data is stored locally during the pilot. No cloud sync. No third parties.
02
Never sold, never advertised against
HealthKit data is never used for advertising or marketing. Sharing requires explicit, per-recipient consent.
03
Export and delete anytime
One tap in Settings. We don't gate it, dark-pattern it, or hold it for thirty days.
06 · Pilot
A closed, invite-only pilot by hand.
We're running a small pilot with operators for whom decision-state is the deliverable. Private TestFlight access, direct line to the team, data stays on your device.
