A general wellness product, not a medical device. Readings are not FDA-cleared, it does not diagnose, and it is not an alarm. Not the XK300 Essence and not equivalent to it.

Every morning Trend · not a diagnosis, not an alarm

Wake up knowing how you actually slept.

Every morning, a clear picture of the night on your phone. No guesswork, no marks on your wrist.

Heart rate and breathing

Read from the chest through the night, thousands of times, while you are still. Not a wrist estimate.

How settled the night was

How long you slept, when you were in bed, and how restless the whole body was, head to toe.

Beside your own nights

Last night next to your last seven and fourteen, so a drift stands out. Your usual, not a population average.

Your limits, your people

Set the ranges you care about and get a notification when a reading falls outside them. Share the view with a family member or caregiver.

A notification describes a change from your usual. It does not diagnose it, and it is not an alarm.

The XKare app Free · iPhone and Android

Your night, every morning.

Sleep, breathing, resting heart rate and how settled the night was, with each night beside your own recent ones. A weekly view when you want the longer story. Free, on your phone.

XKare
The XKare app. Free, on your phone.Pair it with your Somily. Each morning: resting heart rate, breathing and sleep, with trends over 7 and 14 days. Not a substitute for medical advice, diagnosis or treatment.
Why it is different from a ring or a watch Heartbeat Clarity and RRV

Measure. Not estimate.

Heartbeat Clarity: how cleanly each beat comes through

A ring or a watch estimates your heart from the pulse at your finger or wrist. Somily measures the beat itself, as the movement of your chest, and follows how cleanly and regularly it comes through, night after night, beside your own recent nights. No wearable makes this reading.

RRV: the rhythm between breaths

Two nights can average the same breaths per minute and feel nothing alike. Somily keeps the spacing between breaths, not just the count.

The film explains what the radar measures and how that differs from a wearable. In Somily, breathing rhythm is a wellness trend and Heartbeat Clarity is investigational; neither is an FDA-cleared measurement, and Somily does not diagnose.

The science Peer-reviewed · regulator records · independent certification

How it measures, and how we know.

Getting started

Three steps. No prescription.

01

Order online

Direct purchase. No prescription or consultation required.

02

Fast shipping

Ships within two business days, delivery included.

03

Plug in, open the app

Wall-mount near the bed, plug it in, download the free XKare app. It starts working that night.

Where it goes

A disc by the bed. 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.

In the box

Two strips of tape. One cable.

In their words Personal experiences · not clinical evidence

Four people who live with it.

Larry and Susan bought the sensor and have lived with it at home for months. Precious Myers Brown uses it in the facilities she runs. Dr. Serrano is a physician whose facilities use the clinical XK300. Courtney lived with the sensor for several weeks and was compensated for her time. Each speaks from their own experience; none was scripted.

Questions

About Somily.

How is Somily different from the XK300 Essence?

They are different products. The XK300 Essence is an FDA-cleared, prescription medical device supplied through a care provider. Kardian Somily is a general wellness product built on the same underlying radar technology, sold for your own bedroom without a prescription. It is not FDA-cleared and makes no claim to be equivalent to the Essence.

I already wear a smart ring. Do I take it off?

No. Keep it. A ring is good at daytime activity, HRV, skin temperature and sleep stages; we do not do those. We measure breathing and resting heart rate from the chest, through bedding, with nothing worn, and compare each night with your own. Read both in the morning. The side-by-side.

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 paired to its own person in the app. 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.

Can I upgrade later?

Yes. The free plan works from day one over Bluetooth. Max switches on in the app whenever you want it, and it is included for two years with every Somily under the current promotion.

Does it need Wi-Fi?

Not on the free plan. Max sends your nights to the cloud over Wi-Fi so the app can compare them and answer questions.

Can I return it?

Yes. You have 30 nights at home from delivery. If it is not for you, send it back in its box for a refund of the purchase price, less return shipping: $15 within the United States, or the carrier's actual cost if you are returning it from another country. Before it ships, a reservation can be cancelled at any time for a full refund.

Can I pay with my HSA or FSA?

Yes. Somily is HSA and FSA eligible in the United States. Keep your receipt; your plan administrator has the final say.

Is there a camera or a microphone?

No. There is no lens and no microphone. Radar reads movement. It cannot see a face or hear a word.
