Impressive

My cardiologist was interested in more long term monitoring for me, but I did not want to wear a device for 30 days. I do not have any serious issues according to all the tests, but she was interested in capturing my PVCs when they happened and told me about the KardiaMobile devices. I chose the card because it is easy for me to carry it with me and I have already used it several times. A brilliant little device.

Grateful

I'm so grateful for Kardia products. It alerted me to the start of Afib episodes. This led me to my doctor and treatment.

Great product that everyone should have.

It's a wonderful product. I feel less stressed knowing if I'm in AFib or not. I like the fact that I can check and see what's going on when ever I want.

Feeling safe with Kardia Mobile!

Amazing! I grew up with 3 TV channels and no remote,no mobile phone. Now I have a EKG in my wallet. So handy for my husband who has AFib. Great item feel so safe with it in my wallet.

Easy,Convenient,electronic interference issues

the card is easy to use with the app and convenient to carry but retains the issue I had with KardiaMobile...electronic interference frequently gives me "unreadable" results.

Easy to save ECG traces

Can easily power it on, use it to generate the ECG traces and save to PDF The constant pop ups to buy additional features using scare tactics to catch more arrythmias is a serious detraction for what is otherwise a good product with a clean app interface

On-off switch is not intuitive

The switch that turns on the sensors is difficult to turn from off to on. While some difficulty is needed to protect the life of the battery, the need to push the back and front of the switch at the same time is not intuitive. Once one learns how to turn the card on, it functions well.

Good but bad

I like the product but had lots of issues trying to get it to connect. Plus I got the kardiacare but it won't let me sign in says I have to order it again.

Charged Double

I bought two cards. one for myself and one as a gift. To my horror, after paying for the card I found out that I had to pay again for the service the card was to provide. Some gift!!!

Not for inside one's house.

After a day of use/attempted use I realized that the KardiaMobile Card is not suited for use inside a 21st century home, rather it's targeted for use outside of buildings where there's no likelihood of electrical interference. In hindsight had I realized that, I'd have never purchased a product that I couldn't use in my house.
