Kardia

II guess they just changed the method of putting in medications but didn’t use any logic in how it was reorganized or how to record it. It has been most useful in taking ECGs and keeping blood pressure but other than that it has been practically useless and frustrating!

I purchased a 6L max. After one year it is an expensive paperweight without a subscription. I returned to Amazon for a full refund since this trickery is not clearly dislocated. Take your business to companies with more ethical practices.

Useful tool monitoring Afib.

This app really helps me keep track of when and why my heart goes nutz. I'm tryingntonfigure out how to chill out by seeing what makes me freak out in my heart!

They unexpectedly changed everything. There is no editing mode in daily tasks like there used to be. You can no longer make edits to the daily logs. I don’t like the new version at all. The previous version worked well. This update is awful.

This device was working fine in April 2026. Now we can not find a place to use the device that it doesn’t give heart rate of over 150 and results are consistently “Interference” I have tried following all the instructions to resolve. Maybe it only lasts for a year

Why bother not like you’re co. Will get to me with my concern .

Locks up and makes it very difficult to capture any emergent beats, slow to respond.

Every time I go to use the app it locks up. I open up the app and as soon as you see the screen dim a little and it decreases in size and then the screen goes back to a full screen you know it will not work when I hit record EKG. Nothing happens. As a matter of fact, everything locks up I can’t access anything on the app. The only thing that works to correct this issue is turning off the phone completely off by shutting it down and turning the phone back on. This happens every time. If they work out the bugs, this is a great app. It’s a great way to check your heart rate and your heart rhythm. I paid for the full year subscription and I’ve had it less than a month. If this continues , I’ll ask for my money back. While this is a great app when it works, it is just such a hassle to turn the phone off and on, I won’t end up using it. I hope they fix the bug.

Best medical tool I’ve ever used. Safe, easy to use!

worked well

My cardiologist told me to buy this machine when I was having atrial fibrillation. I have used it frequently and being a physician myself, I am amazed at the quality of the EKG tracing delivered by this small device. Also, the ability to print a 6 lead EKG is so convenient. I can send a tracing to any of my doctors and they can print it too. I give this a 10 of 10 rating. I recommend anyone with a heart condition to get one and use it regularly.
