5 Reasons Why This New Heart Monitor Is Like Having a 'Virtual Cardiologist'
A pocket-sized device is changing how adults over 50 keep tabs on their heart, giving them something a smartwatch can't: an accurate, 6-lead EKG in 30 seconds. No membership required.
4.4 out of 5 stars●based on 30,100 ratings|By Kardia|Updated Oct 2026
If you're over 50, you've probably felt it at least once: a flutter, a skipped beat, a sudden racing in your chest that's gone before you can think much of it. You make a mental note to "mention it to the doctor."
By the time the appointment comes, your heart is behaving perfectly, the EKG detects nothing irregular, and you go home with no answer and a lingering question.
That gap, between the moment something feels wrong and the moment a doctor can actually see it, is the problem KardiaMobile 6L was built to close.
1
It’s a 6-lead EKG: six views of your heart, not one
Most people assume their smartwatch already does this. It doesn’t, not really. A smartwatch captures a single lead EKG: one view of the heart’s electrical activity. KardiaMobile 6L records a 6-lead EKG in 30 seconds. That’s six different views, which is how it gives you six times more heart data than any smartwatch.
More leads means a more detailed picture of what your heart is actually doing, and catching more rhythm disturbances that a single-lead EKG may miss.
2
It’s the personal EKG doctors trust
KardiaMobile 6L is the #1 cardiologist-recommended personal EKG. Its used and recommended by doctors worldwide, and validated by hundreds of clinical studies.
You have the option to get your EKG reviewed by a board-certified cardiologist, who can detect 30+ conditions with your 6-lead EKG recording. Order a Clinician Review in the Kardia app for $39 per review, or become a KardiaCare member and get 4 free reviews per year.
“It’s like a virtual cardiologist. You can pull out the device, check your heart rhythm, and instantly know whether or not you’re in atrial fibrillation.”
— Dr. Civello, Cardiologist
3
It’s FDA-cleared: a medical device, not a wellness gadget
There’s a meaningful line between a gadget that estimates and an instrument cleared to detect. KardiaMobile 6L records a medical-grade EKG in just 30 seconds. See instant results on your phone for Normal Sinus Rhythm, Atrial Fibrillation (AFib), Bradycardia, and Tachycardia.

It catches the moment your symptoms actually happen
Heart symptoms are cruel about their timing. They show up late at night, in the grocery line, on a walk, and vanish before any clinic can capture them. Because KardiaMobile 6L fits in your pocket, you can record a medical-grade EKG the instant you feel something off, wherever you are.
“I really enjoy this device and bought one for all my family members. It puts me at ease when I think I am having a heart issue. And it accurately detects when I am.”
— AJ, Kardia customer
5
It lets you build accurate heart health history that you can review with your doctor
Every EKG recording becomes a key milestone on your heart health journey. Make KardiaMobile 6L part of your daily routine to keep tabs on your heart rhythm between doctor visits—whether you feel a symptom or are feeling completely fine.
At your next appointment, turn "I think something felt off" into clear, actionable data your cardiologist can review. KardiaMobile 6L doesn’t replace your doctor—it makes your conversations with them more meaningful.
“Love the device and app. I frequently use it to check after exercise and even on days when I don’t feel good. It complements my blood pressure machine and Smartwatch. All about staying healthy and using the right tools to monitor.”
— Alido, Kardia customer

THE CHOICE
Two ways the next flutter could go.
The next time you feel something off, there are two ways it can go.
You can lie awake wondering, glance at your smartwatch, see another "inconclusive," and try to remember the feeling clearly enough to describe it at your next appointment. By then, the moment is gone.
Or you can pick up your phone, press two fingers on a small device, and have a medical-grade answer in 30 seconds.
Get KardiaMobile 6L →P.S. A single emergency-room copay costs more than KardiaMobile 6L. The difference is, Kardia stays in your pocket and gives you an answer in 30 seconds, backed by a real cardiologist and a report your own doctor can use. And if you don't find it useful, you have 30 days to send it back.
KardiaMobile 6L is not tested or recommended for use with pacemakers and ICDs. KardiaMobile 6L does not check for heart attack and does not replace regular health checkups with your physician. Seek medical attention if you are experiencing any concerning symptoms or if you are having an emergency.
