On your wrist
The JiVa Band reads ECG, heart rate, oxygen, temperature, sleep and activity around the clock and sends it to your care team.

Empowering you to manage your health better.

Health systems pay for illness after it arrives. We built JiVa Labs to find it first.
Chronic disease is now the world's leading cause of death, and most of it is caught late: at the emergency room, the dialysis chair, the intensive care bed. That is the most expensive moment to meet a patient, for the patient, the clinic and the insurer.
2/3
of the world's death and disability now comes from chronic, noncommunicable disease. Global Burden of Disease, 2023.
0million
people died from chronic disease across Africa in 2023. More than half of those deaths are linked to risk factors that can be changed.
0%
of Africa's chronic-disease deaths are linked to high blood pressure, the single largest risk factor, and one whose trend the JiVa Band tracks around the clock.

389:1
What reactive care costs, in one number.
In Kenya, the national payer spends 389 times more to dialyse one kidney patient for a year than it spends looking for the hypertension that put them there. Cancer, heart and kidney disease make up 13.8% of claims but 44.9% of the cost. The pattern repeats in health systems everywhere.
Source: Social Health Authority claims data, July 2025 to April 2026, as reported by Daily Nation and The Star, May 2026.
Everyone pays for finding it late.
Patients
Diagnosed after the damage is done, facing catastrophic bills, lost income and years of treatment that earlier care would have avoided.
Providers
Clinics see a patient at a short visit, then lose sight of them until the next crisis. There is no signal between visits.
Insurers and payers
Claims arrive as expensive, unpredictable emergencies. Medical loss ratios climb, and the preventive benefits meant to stop them go unused.
Our mission
Put continuous, clinically read monitoring on every person living with chronic disease, through the clinics and insurers that already care for them.
Our vision
One million members across Africa by 2031, and the continent's first longitudinal health record built underneath them. Proactive health, clinical precision, financial freedom.
Why now
Continuous care finally costs less than crisis care.
Sensors got small
ECG, oxygen and heart-rhythm sensing that once lived in hospitals now fits in a 25 gram band.
Everyone is connected
A phone in every pocket, and SMS for those without one, carries readings to a care team in seconds.
Payers need it
Rising chronic claims make prevention the fastest route to healthier loss ratios.
The platform
The JiVa Band. A care team on your wrist.
Screenless, swim-proof and light enough to forget. It measures what matters, every minute of every day, and sends it to people who know what to do with it.
Designed to disappear
No screen. No distractions. Just signal.
A woven strap, an alloy frame and nothing to charge every night. Wear it to work, to sleep and into the pool.
About 25 g5ATM, swim-gradeScreenless
ECG and temperature
Touch the plate. Read your heart.
The engraved metal plate is an ECG electrode running on a Texas Instruments sensor chip. Touch it for a heart-rhythm reading, while contact sensors track skin temperature all day.
ECGSkin temperature
24/7 automatic monitoring
Reads you around the clock.
An optical sensor tuned for every skin tone measures heart rate, heart-rate variability, blood oxygen, stress and blood-pressure trends, day and night, with no buttons to press.

Weeks, not hours
Charge it at lunch. Wear it for weeks.
Up to 10 days of continuous monitoring and up to 60 days of everyday use on a single charge. It snaps onto a magnetic charger and buzzes when something needs your attention.

Every reading has a reader
The band measures. The care team acts.
Readings stream to your app and to a nurse-led monitoring desk. A sustained change triggers a call, a check at a Mobile Health Unit, and a clinic visit if it is needed. The band monitors; your clinician diagnoses.

Two ways to join.
Through Star Discover Insurance, with two packages to choose from, or directly through Medicross. Whichever route you pick, you get the same band, app and care team.
Your existing clinical cover stays exactly as it is. JiVa adds what it does not cover, and no service is ever paid for twice.
With Star Discover Insurance
Star health insurance package: cover and JiVa care in one plan. Star SHA+: for SHA members who want additional benefits on top of what SHA covers. Chronic Care is the base of both, with rate-card add-ons or an upgrade to Premium. Acute cover is optional.
Directly through Medicross
Prefer to pay yourself? Subscribe to any JiVa programme monthly through Medicross, online through the JiVa Labs and Medicross sites, or at any Bliss and LifeCare clinic. E-commerce sites coming soon
