Know they're okay. Even from far away.
Leiko is a blood-pressure watch that connects to a caregiving app — so you always know how the people in your care are doing, and they always feel seen. For the people you watch over, for the patients in your care, and for the rhythm of your own body.
Watches are $185 (Leiko) or $230 (Pro). Your $50 deposit comes off the final price. Fully refundable any time before your watch ships.
Who Leiko is for
Caregivers
For the people watching over someone else. Whether you're across town or across the ocean — know that the person you care for is okay, without asking every day.
Managing your own health
For people living with hypertension. Finally understand your numbers — not just what they are, but what they mean, day to day, week to week.
Healthcare professionals
For nurses, community health workers, and coordinators. Monitor the people in your care between appointments — without adding to their schedule.
You can call. You can't reach through the phone.
You can video call. You can send help. You can ask every day. But you cannot reach through the phone and check a blood-pressure reading yourself — and you can't always trust that "I'm fine" is true. Leiko is built for that gap: for the quiet worry between calls, for the check you can't make from a distance.
And if you're managing your own blood pressure, the hard part isn't the diagnosis — it's the days between doctor visits. The readings you're not sure how to read, the trends you can't explain, the question "am I doing better?" with no good answer. Leiko turns your wrist into an honest answer.
Measured. Not estimated.
The Leiko watch inflates a tiny cuff around your wrist and reads blood pressure the same way your doctor's arm cuff does — oscillometric measurement. Not estimated from light sensors. Not an algorithm guessing from your pulse. Measured.
Certified to ISO 81060-2, the international standard for non-invasive blood-pressure measurement.
The watch measures. The app shows. You know.
A calm notification
"Dad's last reading: 128/82 · 20 minutes ago · normal range." You breathe. You know. You don't have to call.
A weekly trend
Seven days of readings, plotted clearly. See whether the numbers are settling or creeping — and what "fine" actually looks like.

"I built Leiko because I needed it myself. Hypertension runs in my family — I carry it too, and I lost my father to the long arithmetic of it. I couldn't find a watch I trusted for my own wrist, so I built one."
Hypertension runs in my family the way other families pass down a surname. I lost my father to it. A few years into my thirties, a doctor told me I have it too.
I went looking for something I could trust — a watch that measures blood pressure the real way, with an actual inflating cuff, not light sensors and estimates. I found the technology. I couldn't find the product built for the people I know — the people watching over someone from a distance, the ones managing their own numbers, the professionals with too many patients and not enough time. So we built it.
