Wellness Monitoring That
Gets Out of Your Way
The Kardian Pebble is for people who want to stay on top of
their wellness without adding anything complicated to their routine.
Easy Setup
Place it on any nightstand. Plug it in. The app connects automatically. There is nothing else to do.
Ambient Monitoring
Over 2,000 measurements captured every day. Heart rate, breathing, body motion, and bed presence, all tracked while you sleep without anything touching you.
Anomaly Detection
The Pebble learns your normal over time and lets you know when something worth paying attention to changes. Simple, clear, and personal.
Early Alerts
No noise. No constant notifications. Just a heads-up when your readings shift meaningfully from what is normal for you.
Wake Up Knowing How You Actually Slept
The XKare app gives you a clear, simple summary of your overnight wellness every morning. Easy to read, easy to understand.
Heart Rate
Continuous resting heart rate tracked through the night.
Breathing Rate
Directly measured breathing rate, not estimated.
Body Motion Index
Restlessness and movement during sleep.
Bed Presence
If the bed is occupied or vacant is tracked automatically.
Sleep Quality Score
A daily score that flags meaningful shifts from your personal baseline.
POBC Score
Trend view showing how your readings are changing over time.
Weekly Trend View
Trend view showing how your readings are changing over time.
Simple Enough to
Actually Use Every Day
Designed for reliable health monitoring
that stays completely out of sight and mind.
Radar, Not Wearables
Uses 60 GHz pulse coherent radar to track your heart rate and breathing while you sleep. No patches, no wristbands, no overnight charging.
Learns What’s Normal For You
The Pebble builds your personal baseline over time. Alerts are based on changes in your own data, not a generic benchmark, so you only hear about shifts that are actually relevant to you.
Privacy First
No cameras. No microphones. The Pebble senses physical motion only when you breathe or when your heart beats. Your data is encrypted and never sold.
Caregiver Access
Give a family member view-only access through the Xkare app so the people who care about you can stay in the loop without you having to report in.
Find the perfect sensor
for your needs
What if you could detect health changes days earlier? Advanced radar technology that monitors health invisibly and alerts you days before changes become serious.
