Personal EKG Monitor for Arrhythmia Detection, FDA-Cleared

Most people don't think about their heart rhythm until something feels off. The KardiaMobile Personal EKG Monitor is a pocket-sized, FDA-cleared single-lead EKG device that captures a medical-grade electrocardiogram in 30 seconds using just your fingertips and the free Kardia app on your smartphone, with no Bluetooth, Wi-Fi, cords, or computer required for basic use.

Key Reasons People Use Personal EKG Monitors

• Catching irregular rhythms between appointments: Heart rhythm irregularities don't always happen in a doctor's office. A personal EKG device lets you record a reading when something feels off and share it directly with your provider for review.
• Ongoing heart rhythm awareness: People managing known arrhythmias or cardiovascular conditions often use personal EKG monitors to stay informed between scheduled checkups, always in coordination with their care team.
• Portable monitoring for active adults: Traveling, exercising, or simply being away from a clinical setting doesn't have to mean a gap in awareness for people who want to track their cardiac rhythm patterns over time.

What's Inside and How It's Made

The KardiaMobile is a compact plastic device with silver sensor electrodes, a 0.96-inch display, and an optical sensor. It measures 3.28 inches long and records a single-lead, medical-grade EKG at 16-bit resolution. The device is FDA-cleared and detects Atrial Fibrillation, Tachycardia, Bradycardia, and Normal Sinus Rhythm. Results display directly in the free Kardia app and can be emailed to a physician or healthcare provider. An optional KardiaCare subscription (additional fee) unlocks additional rhythm detections and access to board-certified cardiologist review from home. The device is FSA/HSA-eligible. Color is Black. Warranty is 1 year.

How to Use a Personal EKG Monitor Day to Day

Download the free Kardia app, place the KardiaMobile near your smartphone, and rest your fingers or thumbs on the silver sensors. Within 30 seconds the app displays your result. No pairing setup, cords, or internet connection is needed for a basic reading. A common friction point is placement: keeping fingers still and maintaining even contact pressure on both sensors throughout the full 30 seconds produces cleaner signal quality than moving or pressing unevenly. For people recording regularly, the app stores EKG history for tracking over time, and individual readings can be emailed directly to a provider. If you opt into KardiaCare, additional rhythm analysis and cardiologist review are available through the app.

Who It's a Good Fit For

This device is suited for adults who want accessible, portable EKG monitoring and are already working with a physician to manage or monitor their heart health. It is compatible with smartphones and works with the Kardia app. It is not tested or recommended for use with pacemakers or ICDs, and it does not check for heart attack. It does not replace regular medical checkups or emergency care. Anyone experiencing urgent or concerning cardiac symptoms should seek immediate medical attention rather than using this device. Compatibility issues with certain Android phones have been reported, so confirming app compatibility with your specific device before purchase is advisable.

What Customers Say

Functionality and ease of use are the most consistently praised aspects, with buyers describing the app as user-friendly and the readings as accurate and easy to interpret. Many users report the device has played a meaningful role in identifying rhythm changes they were then able to discuss with their doctors. Compatibility is the most significant reported drawback: a notable number of users describe connection problems, particularly with certain Android devices, and some report the device not connecting at all. Value for money is divided along similar lines, with satisfied users considering it worthwhile and others citing connectivity failures as the reason it did not work for them.
