Kardia works with the FDA-cleared KardiaMobile or KardiaBand ECG devices— the most clinically-validated mobile EKG solution on the market.

Just touch the sensors on your Kardia EKG device for 30 seconds to capture a medical-grade EKG anytime, anywhere - no probes or wires necessary. Get an immediate result from Kardia's Instant Analysis of Normal, Possible AF, Bradycardia, Tachycardia or Unclassified. Additionally you can choose to send the recording to your physician or to one of our partners for a paid Clinician Review. (Clinician review available in U.S., U.K., Ireland, and Australia only).

SmartRhythm workout monitoring is a system that takes your heart rate and activity data gathered from the Apple Watch during workouts, and evaluates it using a deep neural network to predict your heart rate pattern. If your heart rate differs from the neural network prediction, SmartRhythm will notify you to record an EKG with your KardiaMobile or KardiaBand. Kardia integrates with Apple Health to monitor users heart rate during workout.

New U.S. accounts will have their first EKG sent to our partners for review by a U.S. board-certified cardiologist free of charge (a $19 value within the app). You will be blocked for up to 24 hours from EKG features until the review is complete. This will only happen with your first EKG, all future EKGs on your account will give you a Kardia Instant Analysis, and allow you to review your EKG immediately.

The Kardia app, paired with Kardia Mobile, is recommended by leading cardiologists and used by people around the world for accurate electrocardiogram (ECG or EKG) recordings.Record your heart health data with the medical accuracy your doctor can trust.

NOTE: Requires KardiaMobile or KardiaBand hardware to record an ECG

Mixed feelings

While the idea of this app is great, it doesn’t always work. Despite having a clear signal (“great signal” according to the app) there have been lots of occasions where nothing happens when I put my fingers on the pads. The screen just stays blank. This is pretty bad given you might need to record a fleeting sensation/also paid hundreds of dollars for a device that really should work every time. Also not happy about the monthly fee to save these recordings, when AliveCor are also using your data for their own purposes...what a double whammy. I’d pay a one-off fee to be able to save them but no way am I paying monthly! It feels like a money grab (and data grab!). When it works, it’s great, but overall I feel like I’ve been somewhat taken for a ride.

Great, but...

The technology of this thing is superb, very clever, but not being able to save your ECGs to the journal after the trial period is social injustice, unless you can pay $13AUD a month. Yeap, storing and retrieving your samples from your own phones storage is blocked. You need to reassess your pricing model guys, especially when the device costs more than $200 (whilst treating us as a data commodity). I'd prefer to pay $20 for the app and have this feature native than pay subscription rubbish charges to do something as basic a save you own ECGs. I used to recommend this until the trial period finished.

Given the initial price of the device, I don't understand why I should need a premium account to save my recordings. Most people buy this to keep recordings for their doctors so the history feature is quite necessary. Only way around this is to email recordings to self after taking them, but really you should have made this clear when purchasing. I paid $200 and now have to fork out more to save a recording. Little bit unfair...
The app is great irrespective of this, but I strongly feel that since this is a product designed for people with health problems, a premium account is dumb.
