The hardware
Clinical accuracy. 30-sec ECG. One button.
±3 mmHg, IEC-validated, wear-click-relax. The parts everyone quotes on the box — table stakes, not the reason to buy.
Clinic-grade · one button · sealed to you
Reads like a clinic.
Kept like a secret.
A number at the GP tells you almost nothing — pressure moves with stress, salt, sleep and the hour of the day. The cuff takes a clinical-grade reading at home. The vault turns the pattern into decisions. The raw waveform never crosses over.
Raw waveformoscillometric pulses — stays in the cuff
The readingonly three numbers cross over
Split-data boundary · the waveform never leaves
The difference
Your pressure waveform never leaves your side.
The oscillometric signal and every ECG stay sealed in your vault. No health cloud pooling it. No partner reaching in. Nothing sold.
What you get back
A decision with a reason — not a chart to decode.
"Your morning surge is high — here's what moves it." Every reading resolves to a next step, and the next step carries its why.
Meet the cuff
Carry it anywhere.
Measure it anytime.
A clinical-grade upper-arm cuff that weighs 240 grams and folds into a bag. Automatic inflation, one button, a reading in under a minute — no clinic, no assistant, no white-coat spike.

In the app
A clinical reading, read only to you
Systolic, diastolic, mean arterial pressure and pulse — measured on your arm, computed in your vault, and shown to nobody else. The number arrives with the context that makes it mean something.
- Systolic, diastolic, MAP and pulse from a single press.
- Each reading tagged with posture, arm and time of day — so a spike has a reason.
- A verdict, not a raw figure to look up — what it means and what to do next.
The split-data boundary
How a reading becomes a decision
The old pitch was a health cloud that stored your pressure "for life." This is the opposite architecture: your cardiovascular signal is sealed to you, and only the decision ever travels.
01 — READ
The cuff reads you
The oscillometric waveform and any 30-second ECG — raw, high-resolution, intimate. The actual signal your pressure is derived from.
02 — SEAL
The vault seals it
The waveform lands in your private vault and stays there. It never pools with other people's hearts. It is never uploaded to be sold. There's no cloud copy to leak.
03 — DECIDE
You get a decision
A partner asks a question. The vault answers from your signal and returns a ranked cardiovascular decision — with the reason it chose it — and nothing else.
THE POINT →The raw waveform never crosses the boundary. It isn't a privacy toggle you might forget to switch on — it's the architecture. There is no version of the Humotron Cuff that hands your heart over.

The cuff's lane · cardiovascular baseline
From one-off numbers to a pattern
One reading is noise. The cuff owns the baseline — enough readings in context that the vault can see the shape of your pressure, name what's moving it, and return ranked things to do, each with the reason it picked them.
Pressure — last 30 days
sealed in your vault
111–137systolic
70–88diastolic
Spikes cluster Mon–Thu evenings. Your pressure settles by the weekend — the pattern points at the work week, not your heart.
Ease evening sodium Action
Why: systolic runs 8–12 mmHg higher on high-salt evenings in your own log. The single lever with the biggest move for your pattern.
Magnesium + potassium blend Supplement
Why: baseline creeping up and pulse pressure widening. Supports the vascular tone your trend says is drifting.
Recheck morning surge in 2 weeks Follow-up
Why: waking readings trending up. Two weeks of morning captures tells us if it's a trend or a fortnight of bad sleep.
Every recommendation came from your signal. The partner who fulfilled them never saw a single reading.
30-second ECG
Catch what a number can't
Blood pressure tells you the load. An ECG tells you the rhythm. Irregular beats often arrive without symptoms — a 30-second trace, taken regularly, is how you spot them early. Clinical-grade sensors, three lead options, and every trace sealed in your vault.
- Record a 30-second ECG with Lead I, Lead II or chest lead.
- QRS duration, QTc and PVC count read on-device — flags atrial fibrillation risk.
- Stores 10 ECGs offline. No phone nearby is no problem.

Still looking for a reason?
The readings that actually change something
Pressure is contextual. Take it at the moments that move it, and the vault learns what your heart responds to.
AFTER SALT
After a salty meal
Read once after a high-sodium dinner. See in your own numbers how diet moves your pressure.
BEFORE / AFTER
Around meditation
Take a reading before and after. Watch a few slow breaths land as real numbers.
POST-WORKOUT
Heart recovery
Read after training to see how fast pressure and pulse settle — a quiet fitness marker.
MORNING
The morning surge
Waking pressure is the one clinicians watch. Catch it daily, in the same seat, same arm.

Seals to the vault, not a cloud
BLE 4.0 syncs the reading and the decision — never the raw waveform. Your signal never gets a cloud copy.
Self-use by design
Sized and shaped so you can place the cuff and read yourself — no second pair of hands required.
The only nudge you need
A reminder, not a feed
The value of a cuff is the reading you actually take. One well-timed nudge — tuned to your own pattern, computed in your vault — beats a dashboard you'll never open. You choose the cadence; the vault picks the moment.
- Weekly check reminders you can set and forget.
- Context nudges — "read after tonight's meal" — drawn from your own trend.
- Quiet by default. No streaks, no guilt, no engagement bait.

Frequently asked questions
01
How is this different from a traditional BP monitor?
A chemist's cuff gives you a number and forgets it. The Humotron Cuff reads at the same clinical accuracy, then hands the reading to your vault — where it joins a pattern, gets its context (time, posture, arm), and comes back as a decision with a reason. And unlike a monitor that uploads to a health cloud, your raw waveform never leaves the device.
02
Is it suitable for self-use, or do I need help?
It's built for self-use. Automatic inflation, a single button, and a display you can read on your own arm mean no assistant and no fiddling. Wear it, click once, and relax while it works.
03
Does it really do ECG as well?
Yes — a 30-second, clinical-grade ECG with Lead I, Lead II and chest-lead options. It reads QRS duration, QTc and PVC count on-device and flags irregular rhythms, so you can catch things like atrial fibrillation that a pressure number alone would miss.
04
Where does my data actually go?
Into your private vault, and no further. The oscillometric waveform and every ECG stay sealed to you. When a partner needs an answer, the vault computes it locally and returns only the decision — never the underlying signal. There is no pooled dataset and nothing is sold.
05
Is there a subscription to read my own pressure?
No. The intelligence is included in the one-off price. You never pay a monthly fee to see your own heart, and nothing about you is ever sold to make up the difference.
