What their care team sees

Every night, beside their own usual.

Patrick and Clair both read 78 last night. Only one of them is unusual.

Illustration. The care team reads the measurements and decides what to do. The Essence is not an alarm and does not diagnose. In an emergency, call 911.

The XKare app Free · iPhone and Android

Your nights, on your phone too.

The same XKare app pairs with the Essence. Your care team reads the clinical record on their side; you see your own nights: sleep, breathing, resting heart rate and how settled the night was, each beside your recent ones. Sleep and readiness are shown as general wellness information, not as a diagnosis.

Where it goes

On the wall. Three ways to place it.

Two strips of tape, one cable to a USB plug. Then go to sleep.

The sensor above the headboard
01

Above the headboard

About 1.5 metres from the floor, on your side of the bed. If you share the bed, left or right above you. If you sleep alone, the centre.

The sensor near the bed corner
02

Near the bed corner

It does not have to sit high. Closer to the body, just above the mattress, keeps the cable out of sight.

The sensor behind the headboard
03

Behind the bed frame

Out of sight between the wall and the headboard, as long as the bed does not need to sit flush to the wall and the headboard is not a solid metal plate.

How it measures, and how we know.

In their words

Families, and the people who care for them.

Personal experiences. Not clinical evidence.

How you get it

Through the people who look after you.

  1. Request a callbackYour name, contact details and address. Request the call.
  2. Talk to a remote-monitoring partnerBook a consultation. They call within 24 hours, confirm eligibility, and finalise the prescription and delivery address.
  3. It goes up above the bedOn the wall above the bed, plugged in, a few minutes. See the placements.
  4. Your care team sees the trendResting heart rate and breathing, every night, beside your own recent nights, so a change against your own pattern stands out to them between visits.

Questions

About the Essence.

Can I buy the Essence myself?

No. It is a prescription device, supplied through your doctor, care provider or remote-monitoring programme. If you want a wellness product for your own bedroom, without a prescription, that is Kardian Somily. It is a separate product, not the cleared device.

Who sees my data?

The care team that prescribed it. There is no camera and no microphone; the sensor reads movement, not pictures or sound.

We are two in the bed. How does it know who it is reading?

It collects from the closest body. Mount it above your side of the bed, left or right, and it reads you. Two people, one sensor each, above each side, each linked to its own person by your care team. There is no app to set up: the Essence reports to your remote-monitoring team, not to your phone. Hugging or drifting over for a while is fine: if it picks up two sets of vital signs it pauses, and with thousands of readings a night, a couple of hours on the wrong side barely moves your baseline. See the two-sensor bedroom.

How big is it?

About 9.4 by 4.3 by 9.4 centimetres (3.7 by 1.7 by 3.7 inches), 120 grams. Wall-mounted above the bed. USB powered.

What does it need at home?

A wall socket for the USB plug and the communication module that comes with it. Your provider sets up the connection.

What about the radar?

It transmits at less than a hundredth of the power of a typical home Wi-Fi router, and has been used in hospitals and nursing homes since 2021.
