KardiaMobile Personal EKG Devices

If you've been told to "keep an eye on" your heart rhythm — whether you're managing atrial fibrillation, tracking palpitations, or sharing readings with a cardiologist between visits — a KardiaMobile device puts a clinical-grade EKG in your pocket. Made by AliveCor, these FDA-cleared personal electrocardiogram recorders capture a medical EKG in 30 seconds and detect signs of AFib, bradycardia, tachycardia, and normal sinus rhythm, right from your smartphone.

The choice comes down to how many leads you want and how you carry the device. The AliveCor Kardia Mobile ECG (4th Generation) is the classic single-lead recorder — place two fingers on its pads and pair with the free iPhone or Android app for an instant reading. The KardiaMobile Card is a single-lead device sized like a credit card, so it lives in a wallet and travels anywhere. For a fuller picture, the KardiaMobile 6L records six leads and delivers six views of the heart in 30 seconds, giving your doctor closer detail than a single-lead trace can provide.

A common question: do you need a subscription? The devices work without one, but KardiaCare membership unlocks advanced determinations, monthly heart reports, and cardiologist review. Readings can be emailed as a PDF to your physician regardless. Setup takes minutes — download the app, follow the pairing prompts, and record. No gel, wires, or clinic visit required.

These recorders suit anyone monitoring a diagnosed arrhythmia, patients on rhythm-control medications, and health-conscious users who want documentation to bring to appointments.
