~27sQuick Tip
The KardiaMobile 6L model records a 6-lead EKG and gives more detailed information than the standard 1-lead model. Talk to your doctor about which version is best for you.
Pair the device with your phone
~21sWarning
A phone case with a thick rubber bottom can sometimes block the device's signal. If recording fails, try removing your phone case first.
Take a recording
~29sQuick Tip
For best results, rest your elbows on a table so your hands are steady. Moving too much during a recording can create interference that makes the result harder to read.
Read your result
~29sWarning
KardiaMobile is not a replacement for emergency care. If you have chest pain, severe shortness of breath, or feel like you are having a heart attack, call 911 right away rather than taking a recording.
Share your recording with your doctor

KardiaMobile is a small credit-card-sized device made by AliveCor that pairs with your smartphone. When you press your fingertips against it for 30 seconds, it records an electrocardiogram — the same type of reading a doctor's office uses to look at your heart rhythm. The result is displayed right on your phone screen and can be saved or sent to your doctor.
Many people use KardiaMobile because they feel occasional heart flutters, skipped beats, or palpitations but cannot capture them during a regular doctor visit. With this device in your pocket, you can record a reading the moment you feel something unusual and show your doctor exactly what was happening.
The Kardia app can automatically flag readings as "Normal," "Possible Atrial Fibrillation," "Unclassified," or "No Analysis." Atrial fibrillation — often called AFib — is a type of irregular heartbeat that can increase the risk of stroke, so catching it early matters. The device is FDA-cleared for detecting AFib.
You do not need any medical background to use KardiaMobile. The app walks you through every recording and stores all your results in a history log. You can also pay for a Kardia subscription that lets board-certified cardiologists review your recordings and send you a written report, which you can then bring to your own doctor.
KardiaMobile works with most iPhones and Android phones. The device itself costs around $99 and does not require a subscription to take and store recordings at home.
