Amazing Product- But You Have To Pay a Monthly Fee!!
I’m torn between a three and four star review.First of all, this is an amazing device. I was diagnosed with Paroxysmal A Fib and it has been a great help for keeping track of things. It has helped with anxiety related to having A Fib as when you feel funny you can take a reading and find out if you’re in A Fib or not.However it has some pretty serious issues. First and foremost, there is a monthly fee that is $9.99 American (!) that is above and beyond the cost of the device. This was unwelcome news. You cannot see previous EKG readings unless you pay the monthly fee. You can’t keep track of your readings without it. It is ridiculous. YOU CAN’T EVEN SCREENSHOT the readings to save on your phone, they specifically block the ability to do so! If there was a modest yearly fee I think I would be okay with it but nearly $15 Canadian a month to have access to your EKG readings is insane.Also, it seems to pick up background frequencies sometimes resulting in wonky readings that can look really freaky.Overall this is a handy tool if you can afford the monthly fee, otherwise it is a total pain in the butt to try to keep track of the EKG readings. You can email them to yourself but this is a pain.My sincere hope is that Kardia makes this product more affordable and either eliminates or greatly reduces the monthly fee. When I had the free thirty day trial I was very happy with the device, being able to see your past readings was very cool and very helpful. I could show them to my doctor and it was a really excellent tool. However without the ability to save the EKGs it has become a pain to show EKGs to my doctor. I have to email them one by one as they are taken and then later on print them and bring them to my doctor.

Super-Elastic – February 19, 2024

Edit: I am removing one-star because they oddly do not offer a one-month trial of their service for customers who purchase both the this device and the band for the Apple watch. The one-month trial is one per customer, not one per product, and the Apple watch band fails to work unless you pay for the subscription. It’s an odd way to honor customer loyalty.——————-This is a truly amazing, one-of-a-kind device. For certain individuals, this could be a literal lifesaver. Why just 4 stars, then? I think there’s a little room for improvement, particularly on the Android side of things. The quality of the reading is very dependent on the particular model of phone, because it communicates with the phone, not by WiFi or Bluetooth, but by ultrasonic tones. Phone microphones are not necessarily optimized to receive sounds in this range.On many phones I tested it works well enough to distinguish between most cases of atrial fibrillation and normal sinus rhythm (but, then, so does just taking a radial pulse). But for more subtle abnormalities, such as differentiating atrial fibrillation from multifocal atrial tachycardia, it is essential to be able to discern P waves and determine if there is an isoelectric baseline. Consequently, a good recording, versus a slightly noisy one, can make all the difference.I am an Android user and did not have an iPhone until after I purchased this device. I was disappointed to see the latest generation of Android phones were not included on the official list of manufacturer-approved phones. (Just because you can download the app from Google Play on your phone, doesn’t mean that it will necessarily work well, or even at all, on that phone.)The following are the phones I tested and the results, in case it is helpful to others:OnePlus 5T – This had been my current phone, a great Android device that I very much love. KardiaMobile does not really work at all with this phone, unfortunately. Initially there was mainly a “no signal” indication with a rare “weak signal” being reported by the app. After multiple attempts, with my fingers moistened and the KardiaMobile sitting on a desk, I was able to get a shaky, noisy, and artifact-ridden baseline read completed. I sent it in for “human” review of the initial read. It (somewhat surprisingly) passed muster as normal sinus rhythm and allowed me to then begin using the app and take additional recordings. I subsequently discovered that if the device is placed on the back side of the phone (noting that a mount is provided) I could get a half-way decent reading, but I still was not confident about it. Not surprisingly, it is not on the list of approved phones.Samsung Galaxy S7 – This was the phone I used before my OnePlus 5T. I still had it in my closet but was loathe to go back to it because it grew laggy, battery life significantly shortened over time, and I hate the TouchWiz complications that Samsung layers on to Android. In fact, it may be no exaggeration to say that I’d rather have a stroke than go back to this phone–just kidding. Nevertheless, of all the phones I tested, this one works the best, with a consistently strong signal and clear recording, rivaling or even exceeding an iPhone X, which I eventually settled upon (because the old S7 was simply not an option for me). My findings were consistent with it being listed as an approved phone by the manufacturer.My initial preference was for a Google Pixel 2 or 2XL, which are on display at Best Buy. However, in demo mode, the app could not be installed. Sure, I could ask people I know to test KardiaMobile out on the various phones they own, but I don’t really want to go into a long explanation of my motives for doing and concern them with potential health issues.Samsung Galaxy S9+ – I tried two different samples at Best Buy. Surprisingly, I was able to install the app in the demo mode at the store. The first device was connected to the charging/anti-theft cord and the salesman would not allow me to unplug it. However, he did graciously allow me to try out his personal Galaxy S9+, unplugged it so that I could be sure it was free of 60hz or other electrical interference from charging. The recordings were similar on both units: Although the signal was reported as strong, there was a high frequency, very fine and regular interference pattern (similar or worse to recordings on other units when the “enhance” option in the app was switched off). Strike that one off the list. I did not try taking a reading with the device fixed to the back of the phone, nor did I test a Galaxy S9.LG G7 ThinQ – I tested this at a T-Mobile store. It was connected to the charging/anti-theft display. Again, I was surprised I could install the app in demo mode and also surprised that the salesman wouldn’t disconnect it for me, even though I informed him I’d buy it outright on the spot if it worked well. Surprisingly, it worked pretty well and was borderline acceptable. In a quieter room, disconnected from external power, without me performing contortions to keep the phone from retracting onto its anti-theft tether while holding the KardiaMobile, it may even be entirely acceptable. However, I wasn’t willing to take that risk and struck it off the list.Huawei Mate 10 (not the Mate 10 Pro) – This phone is on the approved list. It was not available to try at any local retailer, so I ordered it from Amazon. I was disappointed with the phone both as an Android device and its specific use with KardiaMobile. It was as bad or worse than the Galaxy S9+. I don’t know how it passed testing from KardiaMobile’s manufacturer, unless I happened to get a faulty unit.So, at that point, really the only semi-current Android device was the Galaxy S 8/8+. I didn’t try either because I couldn’t imagine spending a lot of money on a device that was already one generation-old (and I’m also not a fan of Samsung’s implementation of Android). I also called the KardiaMobile manufacturer technical support. They were easy to reach but had no updates on any newly approved Android phones. I was therefore resigned to switch to an iPhone.I went to an Apple Store. They would not let me install an app on a phone, so I had to purchase a phone as an article of faith, given that virtually all reasonably recent iPhone models are listed as working by the KardiaMobile maker. Fortunately, they have a generous 2-week no-strings return policy (or at least that’s what they say). I am pleased to say that the device works well on an iPhone X. In contrast to my experience with the OnePlus 5T, there seems to be a better recording when the KardiaMobile is placed on a desk, rather than the back of the phone. The iOS app also seems a little more robust than the corresponding Android app.The KardiaMobile will be useless if I don’t have it with me. That was my main reason for not using with my old Galaxy S7. I simply could not imagine carrying around two phones (with the S7 only being used for KardiaMobile, but not as a phone), using two different types of cables to charge them. I wish that the KardiaMobile manufacturer made a case that could incorporate the device on the back of iPhone X, but they only do so for the iPhone 7/8 (and both of those were too small for me for the basic phone functionality I needed). Additionally, as noted, I felt that the device worked better when placed alongside, rather than on the back of the iPhone X.For the time-being, I am carrying the KardiaMobile, encased in the separately purchased manufacturer’s felt case, in a K.So minimalist stretchy, fabric wallet, where it fits quite well, alongside my usual credit cards, cash, and driver’s license.I still miss my OnePlus 5T. I feel that Android is a better OS (or at least I prefer it) and that the OnePlus 5T is, in many regards, superior to an iPhone (with the exception of the camera). Nevertheless, for me, it s a compromise worth making. There is also the possibility of adding the KardiaMobile band to an Apple watch, whereas there is no similar watch-based solution for the Android platform.

I can’t express enough how impressed I am with the Kardia Mobile 1-Lead Personal EKG Monitor! This device has truly been a game-changer for me and my health monitoring journey.First and foremost, the setup was a breeze. The instructions were clear and straightforward, and within minutes, I had the device synced up with my smartphone. The compact size of the monitor makes it incredibly convenient to carry with me wherever I go.The real-time monitoring feature is outstanding. Being able to take an EKG reading on the spot and see the results immediately on my phone screen is both fascinating and reassuring. The clarity and accuracy of the readings are remarkable, and I feel more in control of my heart health than ever before.The app that accompanies the monitor is user-friendly and intuitive. It not only displays the EKG readings but also provides insights and trends over time. I love how I can easily share the data with my doctor, allowing for more informed discussions during my appointments.One of the standout features for me is the ability to track symptoms. I can add notes about how I’m feeling during each reading, which has helped me identify potential triggers or patterns in my heart’s behavior. This feature has proven invaluable in understanding my health better.The device’s battery life is impressive. I appreciate that I don’t have to worry about constant recharging, especially during trips or busy days.Overall, the Kardia Mobile 1-Lead Personal EKG Monitor has provided me with a sense of security and control over my heart health that I didn’t have before. It’s easy to use, provides accurate results, and integrates seamlessly into my daily routine. If you’re looking for a reliable and user-friendly EKG monitor, I wholeheartedly recommend this product. It’s truly a 5-star addition to anyone’s health toolkit.

Good Portable Heart Rate Monitor
This my second purchase because similar device I purchased few years ago started malfunctioning only after a couple of years.That device was good to start with & was very useful when I was even able to record someone’s heart rate & rhythm during an episode which even a 2 week recording by the hospital devices couldn’t. But then I had trouble in recording even with fresh batteries. Sometimes it would work by taking the battery out & rubbing it before placing it back again. But that was too late if you wanted to record very quickly.Having read some recent positive reviews & possibly some issues addressed I decided to go for the same device again. OK for now; let’s see how it behaves.

Revision to below concerning signal. When using as shown in photo with Kardia on left side of the phone, signal picked up fine. I still recommend the more expensive model is probably better for those who feel they need the device. Mine gave me results saying possible atrial fibrillation on quite a few occasions. According to my cardiologist, it was fooled by the fact that I have a low heart rate and often have an irregular spacing between heart beats (which apparently are not as much of a concern as AFIB.Only issue I had was acquiring a good signal to phone. I laid my phone on table or lap and held the device just above top of my iphone. It has a small sweet spot. Other than that, it worked great. If you want or need one, worth the money. If I were to buy again, I would get the more advanced one that has more contacts to record a more detailed EKG pattern.

Great personal ECG/EKG
It gives good results when it works, with the sinus rhythm matching that on another device which doesn’t record. The ability to review history is great. The downside is trying so many different locations to get it to work for the full 30 seconds, without complaining that it has stopped because of electrical interference. It is possible that the leather case for the phone might affect things. I’d certainly buy it again if I lost or damaged it.

I’ve had chest pains, fluttering, fast heart rate, dizziness/lightheadedness and shortness of breath for a while now. I’ve had a stress test, heart ultrasound, multiple EKGs and all have missed my AFIB. This thing has finally confirmed what I thought was going on and caught it. Now I just need to make an appointment to bring it up to my heart doctor. I have PTSD and anxiety from combat so my doctors at the VA wrote it it off as symptoms of panic attacks. Glad I listened to my body and took the initiative to self diagnose. I come in and out of AFIB pretty often so it’s understandable to miss it, but when you know it’s not all in your head it’s better to be safe than sorry. If you have symptoms, I highly suggest purchasing this portable device and test yourself when symptoms occur. Your heart isn’t worth the risk of not knowing what is really going on.

The perfect, portable ECG device to take charge of monitoring your HEART health!!!
Well, we all become complacent about our heart health until it becomes problematic. This is why I bought this device as given a recent discovery of an issue with my heart, I needed to monitor both my BP and whether there were any anomalies occurring with extra arterial or ventricular beats. I chose this device, as it was compact and reasonably priced.I received the device quickly, however the seals on the box were broken. This was reported back to AliveCor, who quickly despatched a replacement.IN THE BOX————–1. The Kardia Device2. Phone Attachment case with 3M Sticker to attach to your phone*3. Free Trial Access to 30 days of the Premium service. The premium service costs £9.99 per month (or £99.99 per annum as a 20% discount is offered).4. Instruction card to allow for quick set-up including registering your account with your personal details.* I am mentioning the phone attachment case, which is about £10, as I did not realise this, was included and nearly ordered it as well, so please note you get it included. Personally, I feel the case is probably the extra piece of kit that most would prefer to be included, as it offers the option of carrying the Kardia device with you, and using more securely on a table or desk, given the sensitivity to movement of the device. The case retails at about £24.99, which is quite expensive.HOW IT WORKS_______________You simply download the app from the App Store and pair your Kardia device and phone via Bluetooth.ON-APP WELCOME SCREEN———————————There are currently the following sections for tracked data: -1. Electrocardiogram (EKG) – History, Last recorded EKG and button to 2. SmartRhythm Monitoring (which requires an iWatch AND Premium service to utilise).2. Blood Pressure (History + ability to add blood pressure readings at your will)3. Resting Heart Rate (History + add Resting Heart Rate – but this is a premium feature)4. Weight (ability to add your weight)5. Medication (Ability to add your medications and monitor how these impact on your heart health – but this is a Premium Feature!)6. Insights (Premium Feature??)PROS——-1. This device is compact and simple to use.2. Easy to take a reading on the go, and more importantly when these issues occur you are armed unlike when employing a device loaned from a hospital or cardiology service.3. This kit is medical grade, which means it’s accurate and your cardiologist will accept the results as being accurate.4. EKG report instantaneously reports whether the reading is normal or not, and a graph is produced for download and retention.5. Can be linked directly to your doctor or cardiologist via a code.6. You can request a comprehensive analysis by a cardiologist of any reading at the click of a button on-screen and at a cost of £5.00.7. Notes and voice recordings can be added to each EKG reading, so you can add symptoms, to provide a history or just to understand when you might have a future issue.8. The cost is very reasonable for the accuracy and ability to run real-time EKGs for yourself.9. There is a lot of additional information in the App, like Heart Education and access to external heart related resources/institutions.10. The phone attachment is included, so the device can be clipped ono the back of your phone for use on the go.11. The Colour-Coding of reports and data to show GREEN = Okay, YELLOW = Above Normal is a great and simple feature.12. US customers can get the device replaced for $19.99 if lost/stolen with Premium Membership.CONS——1. There should be a manual, even if small to explain the basic features. For example it is possible adjust the length of the EKG recording in the settings from 30 seconds to 1, 2, 3, 4, or even 5 minutes.2. Many of the features are Premium, which means it becomes costly to access these services, like medication and resting heart rate.3. The reports could be more detailed, especially given all the potential this device has and information collated.4. Too sensitive to movement, as my cardiologist discounted some anomalies as slight movements.5. I did one Clinician Review and it is returned as “UNACCEPTABLE- Baseline noise makes it difficult to do an accurate analysis; consider repeating study”. However, what noise does this refer to and why charge £5.00 if they state this?6. Explanation of reports is too basic, and unless you have a little knowledge or real concern about symptoms, the device does not alert follow up.7. There is no reduced price replacement device for Premium UK members!CONCLUSION—————-Well, overall this is a very handy device, which allows you to take charge of your health. However, I would say you do need to read up and learn a bit about EKGs also to understand how to read them yourself a bit, to accurately be able to monitor whether there is movement affecting the readings. The App could be much stronger, integrating the features and allowing a longer trial period. The 30-day trial period is not enough to understand all the features and evaluate the device’s worth. Clearly, most are repeat customers if they gain value from something, and will have no qualms about investing in their heart health.I do think that a short manual would be ideal with this device, as there is a lot in the App and much to understand. You will note the Analysis Report above in the images states “no symptoms” but I do not always note the symptoms, as I want to see whether the report will come back with an issue. I did not realise that written notes could be added later.The phone attachment although seemingly good to allow access to the App on the go, may be problematic. It is perhaps better to be sat at a desk with the device flat, rather than in the air where movement can affect the readings. Personally, I would have preferred the snap-shut case to carry with me, rather than the phone attachment, which is not so easy to remove the device from.RECOMMENDATION———————–Well, having learned a bit about how to read EKGs, I do have peace of mind about my heart. This device is worth the price, especially as it is medical grade to know your heart is functioning properly!!!
