Kardia Mobile is a portable electrocardiogram (ECG) that can detect atrial fibrillation (AFib) and other heart conditions.
This device is particularly useful for people who are at high risk of heart conditions, such as those with a family history of AFib or those who have already experienced a heart attack.
Kardia Mobile's accuracy is impressive, with a 99% accuracy rate for detecting AFib, according to the manufacturer's own testing.
It's also worth noting that Kardia Mobile is a relatively affordable option, with a one-time purchase price of $199, which is a fraction of the cost of a traditional ECG machine.
What It Can Do
KardiaMobile is a reliable and portable device that can help you monitor your heart health from home. It's clinically validated, CE marked, and FDA-cleared, making it a trustworthy tool for checking your heart rhythm.
The device takes an ECG, a picture of your heartbeat, which is similar to the ECG you receive from your doctor's office. This allows KardiaMobile to identify if you're in atrial fibrillation, a condition that requires long-term management.

You can use KardiaMobile to track your heart health at home, and the device can send you an automated response if your heart rhythm is abnormal. This can be a big help in managing your condition and catching any potential issues early.
The device records images or strips of your heartbeat, which belong to you. If you choose, you can send a copy of the images to your doctor's office for further review. This can be especially helpful if you have symptoms that you're not sure are related to your heart health.
Some common risk factors for heart disease include smoking, high blood pressure, high cholesterol, prediabetes or diabetes, obesity, and a sedentary lifestyle. Talking to your doctor about managing these risk factors can be an important part of maintaining your heart health.
Here are some of the key benefits of using KardiaMobile:
- Identifies atrial fibrillation and sends automated responses
- Records images or strips of your heartbeat for future review
- Can be used at home without a prescription
- Is clinically validated, CE marked, and FDA-cleared

How It Works and Limitations
KardiaMobile is a small, portable device that's about 3 inches long and can be easily carried in your pocket or attached to your smartphone. It's designed to help you track your heart health between doctor's visits.
The device has a simple design with a place to put your fingers if you feel symptoms, and it transmits your ECG results to the Kardia App on your smartphone in about 30 seconds. This makes it a convenient tool for monitoring your heart health at home.
KardiaMobile has FDA clearance to detect irregular heartbeats and rhythms, but it's not a full FDA approval. Instead, it's cleared because AliveCor showed that it has similar benefits to other products that are cleared or approved by the FDA.
The device is compatible with most smartphones, but it's not compatible with all newer Android and Apple products. Be sure to check the most recent compatibility list before purchasing.
Here are some common risk factors for heart disease that you should discuss with your doctor:
- Smoking
- High blood pressure, or hypertension
- High cholesterol
- Prediabetes or diabetes
- Obesity
- Sedentary lifestyle
It's also worth noting that KardiaMobile can't detect a heart attack, and it's not compatible for use with implantable cardioverter defibrillators or pacemakers.
CardiMobile vs Apple Watch: Recommendation
I typically recommend the KardiaMobile, as it's easy to use and provides good quality ECGs that my office can determine the rhythm from.
The KardiaMobile is also a more affordable option, especially for those looking for a home monitor for atrial fibrillation.
For someone who wants the added features of a smartwatch, such as messaging, phone, and music options, the Apple Watch might be a good choice.
However, if you're looking for a device specifically for at-home AFib monitoring, the KardiaMobile is the way to go.
It's worth noting that Nirave, who had a heart attack at 33, recommends the KardiaMobile for its value and ability to provide medical-grade EKGs from home.
In fact, he thinks the KardiaMobile is worth every penny, especially for the mental relief it brings from health anxiety.
Ultimately, it comes down to what you're looking for in a device: if you want a dedicated AFib monitor, the KardiaMobile is the better choice.
A Valuable Subscription
The KardiaCare subscription is a valuable option for those who want to take their heart health to the next level. It costs $9.99 per month or $99 per year in addition to the Kardia Mobile 6L hardware.
The KardiaCare subscription includes advanced determinations, insights, and clinician reviews from cardiologists working for an AliveCor-affiliated independent, physician-owned medical group. This can provide peace of mind and help you stay on top of your heart health.
With KardiaCare, you'll also get heart health summary reports, automatic sharing of your EKG, and tracking of your medication. This can be especially helpful if you're managing a condition or taking medications.
However, one user found that the clinician reviewing the EKG didn't have access to their wider medical record, which limited the usefulness of the service. This was a key factor in their decision to cancel their subscription after two years.
