Quick summary
Kardia is a free iPhone application from AliveCor that lets users record clinical-grade electrocardiograms at home. Listed in the App Store under Education & Reference → Medicine, the app pairs with FDA-cleared Kardia hardware to capture short, accurate readings that help detect common rhythm abnormalities.
Supported hardware and compatibility
- KardiaMobile 6L (six-lead personal ECG)
- KardiaBand, KardiaMobile (single-lead options)
- iPhone (requires compatible model and iOS version)
These devices are cleared by the U.S. Food and Drug Administration for their intended ECG uses and are designed to work wirelessly with the Kardia app.
Core capabilities
- InstantAnalysis provides immediate feedback (e.g., normal, possible atrial fibrillation, slow heart rate, or fast heart rate).
- Store and review your ECG history from home so you can monitor trends over time.
- Capture medical-grade ECGs without adhesives, wires, or gels, anytime and anywhere.
- Share recordings directly with your clinician or submit them for expert review through AliveCor’s partner network.
How recordings are handled and reviewed
Clinicians can receive ECG recordings remotely, and users may opt to have a cardiologist or certified cardiac technician review a tracing for a more detailed interpretation. The app supports exporting and sending data to providers to help integrate home ECGs into medical care.
Why clinicians and patients rely on it
Kardia devices and the accompanying app are widely used and recommended by many cardiology professionals for obtaining accurate, on-demand ECGs. The ability to produce quick, reliable tracings at home makes it a practical tool for tracking arrhythmias and sharing objective data with care teams.
Alternatives and notes on pricing
- Dexcom G7 — often mentioned as an alternative by some users; note that Dexcom is primarily a continuous glucose monitoring system, and availability or cost may vary.
- Other cardiac-monitoring apps and wearables exist; compare features, device requirements, and professional review options before choosing one.
Always consult your healthcare provider about how recordings should be used in your care plan.
