What’s the Difference Between KardiaMobile, KardiaMobile Card, and KardiaMobile 6L?

Learn the differences between our Kardia personal EKGs and how they stand out against the rest.

There are plenty of wearables out there today, but not all are created equal. Let’s discuss how KardiaMobile, KardiaMobile Card, and KardiaMobile 6L differ, and why they stand out against the rest.

What is KardiaMobile?

KardiaMobile is a smart device that can record a medical-grade electrocardiogram (EKG) right on your smartphone. EKGs measure the electrical activity of your heart and are used in hospitals to detect irregularities with your heart rate or rhythm, which may be indicators of a heart condition such as atrial fibrillation (AFib). KardiaMobile records a single-lead EKG, which provides you and your doctor with reliable information on your heart health. KardiaMobile can detect AFib, Bradycardia, and Tachycardia, with more determinations available with a KardiaCare membership.

What is KardiaMobile 6L?

KardiaMobile 6L is the world’s only FDA-cleared, 6-lead personal EKG. Six leads means 6 times the heart data, giving you and your doctor the most detailed view of your heart you can get outside of a hospital. KardiaMobile 6L can detect 6 of the most common arrhythmias, including AFib, Bradycardia, Tachycardia, PVCs, Sinus Rhythm with Wide QRS, and Sinus Rhythm with SVE. KardiaMobile 6L is only available with a KardiaCare membership, which gives you access to enhanced EKG analysis and exclusive features that will help you better manage your heart health.

What is KardiaMobile Card?

KardiaMobile Card is the first and only credit-card-sized personal EKG to be cleared by the FDA. It’s thin and light enough to fit perfectly in your wallet, so you can take it with you anywhere. KardiaMobile Card uses Bluetooth to connect to your phone and record a medical-grade, single-lead EKG in seconds, no WiFi required. KardiaMobile Card includes 1-year access to KardiaCare, our one-of-a-kind heart health membership that will help you manage your heart health on the go. Members unlock exclusive features in the Kardia app and have the ability to detect six of the most common arrhythmias, more than any other personal EKG.

How does Kardia compare?

From Apple Watch and Fitbit, to Amazon Halo and other wearables or fitness trackers, there’s a lot to consider when deciding what you truly need in a device. One thing is for sure, if you’re looking for a device that provides reliable and detailed information on your heart health, look no further than Kardia. Here’s why:

The most FDA-cleared determinations

Kardia devices can detect more arrhythmias than any other device. They detect what’s going on with your heart rather than simply indicating you have a “low heart rate” or “high heart rate”. It’s the next best thing to having your cardiologist at your side.

Unmatched clinical validation

Kardia devices are the most clinically-validated personal EKGs in the world, meaning they have more research and clinical studies to back up the technology than any other device (over 150 peer-reviewed articles).

More heart data

KardiaMobile 6L records six leads of heart data—information that you can’t get with a fitness tracker. If you’ve been diagnosed with a heart condition, or suspect there may be something wrong with your heart, KardiaMobile 6L will give you the most in-depth view of your heart from home and provide invaluable information for your doctor.

Portable and convenient

Kardia devices, especially KardiaMobile Card, are small enough to fit in your wallet, pocket, purse, or even clip to the back of your phone. It’s easy and convenient to bring with you, but you don’t have to wear it 24/7. Simply take your KardiaMobile Card out when you feel a symptom and start recording your EKG instantly, no matter where you are.


Where some wearables can cost upwards of $400, Kardia devices are less than half of that. Our devices start at just $79, giving you a significantly more affordable way to care for your heart.
