Is there a good Android app that can help me check my heart rhythm for irregularities like atrial fibrillation?

Kardia is a mobile application developed by AliveCor Inc. that focuses on personal heart health monitoring, specifically for detecting arrhythmias such as atrial fibrillation. It works in conjunction with a thin, credit-card-sized recorder to capture medical-grade electrocardiogram (EKG) readings directly from an Android smartphone. The app analyzes these readings in real-time, offering detection for atrial fibrillation, bradycardia, tachycardia, and normal sinus rhythm, which can be useful for individuals managing heart conditions or seeking early warnings. Users often find it practical for regular checks, especially since it stores data for review and sharing with healthcare providers. However, some drawbacks exist: the free version includes core features, but advanced tools like medication tracking require a monthly subscription of $9.99, a point of criticism in user reviews. Interface issues, such as cumbersome steps to view EKGs in landscape mode, can also hinder the experience for those preferring a more streamlined layout. Despite these limitations, Kardia's portability and ease of use make it a reliable option for home-based monitoring, particularly when recommended by cardiologists. It supports both single-lead and six-lead recordings depending on the device, catering to varying needs. Reviews indicate that performance may vary with Android phone models, suggesting compatibility checks are advisable. Overall, while the subscription model and occasional upsell prompts are noted imperfections, its effectiveness in arrhythmia detection remains a key strength.
