I have to take a reading 5 or 6 times to get one that doesn’t say “unreadable”. And yes I am sitting still the whole time ### 4/5 — great device i *2026-08-23, version 5.60.0* it is very easy to use it shows what i have i would like more detail but its great ### 4/5 — iPhone 17 Pro *2026-08-22, version 5.60.0* Got new IPhone & Case, but it is a difficult challenge every day getting my KardiaMobile device to record my EKG… often have to retake a reading 3 to 5 times after moving fingers around or wetting tips or adjusting the pressure… never had this issues before with my old Android phone. ### 5/5 — Easy to use *2026-08-21, version 5.60.0* So easy to use and then email my cardiologist. ### 5/5 — Great tool for my health tracking *2026-08-21, version 5.60.0* This has been a reliable app and is so easy to use. ### 5/5 — Great indicator *2026-08-20, version 5.60.0* I purchased the unit about 4 or 5 years ago and used it with confidence. Medication helped control my Afib for a number of years until last night. I went into a racing heartbeat for nearly 8 hours. Unfortunately, the battery was dead. Replaced it today. ### 3/5 — subscription *2026-08-20, version 5.60.0* I shouldn’t have to keep paying for a subscription when I already bought the unit. Hundred dollars a year and that’s what I paid for the unit. ### 5/5 — My review *2026-08-20, version 5.60.0* Kardia keeps me informed during the 6 months between visits to my cardiologist. ### 5/5 — Lifesaver *2026-08-19, version 5.60.0* A botched surgery ### 5/5 — Saved me from serious issues *2026-08-19, version 5.60.0* When the 6 lead device said I had afib I doubted it. They replaced it with a new one. Same results. When I discussed it with my dr he gave me a 12 lead ekg and then sent me to the er. This has had a profoundly positive effect on my life. I use my device each and every day! Thanks. I am grateful. ### 5/5 — Representative was great *2026-08-17, version 5.60.0* Justin was professional and was able to diagnose the cause of the malfunction right away. Good job Justin ### 5/5 — Life Connection *2026-08-17, version 5.60.0* Excellent ### 3/5 — Great but flawed *2026-08-17, version 5.60.0* This little bit of kit has been invaluable in giving me assurance and providing information to medical staff. The fact that it is expensive and not everyone can afford it, is compounded by the fact you can’t change the battery, so once it’s flat it has to be replaced. Not acceptable in my book!!! ### 5/5 — Heart beats *2026-08-15, version 5.60.0* This device is my lifeline. ### 3/5 — Not for me *2026-08-15, version 5.60.0* Kardia keeps saying I have afib 2 doctors say I do not. But I do have a premature heartbeat. ### 5/5 — Extremely useful *2026-08-15, version 5.60.0* I find this app very useful in guiding me on what my heart is doing! ## Most critical reviews (10 lowest-rated) ### 1/5 — Readings *2026-08-28, version 5.60.0* Computer interpretations of the EKG’s are very often not accurate. Some are overread; poor correlation with a real EKG. ### 1/5 — Forced subscription *2026-08-26, version 5.60.0* The product works ok. If you’re not perfectly still there is a lot of artifact on the reading. However it’s absolutely ridiculous that you pay over a 100 dollars for a product and you have to pay for a subscription otherwise it doesn’t work! I would not recommend. ### 1/5 — Nacho *2026-08-24, version 5.60.0* Only works about have the time and def don’t work when you think your have an episode ### 1/5 — Piece of junk *2026-08-22, version 5.60.0* Have bought 2 Kardia Mobile and 1 Kardia 6L. They work for a few months and then just stop working. When working they want to “upgrade” you for $15/month to get it to say PVC and 2 other common waves forms. Absolute junk. Worthless app and devices that are incredibly cheap and don’t last longer than 3 months, based off experience with 3 different devices. Save your money. ### 1/5 — PVC’s *2026-08-11, version 5.60.0* Kardia shows PVC’s but does not mention the findings in the results. ### 1/5 — Poor System Change *2026-08-11, version 5.60.0* Your app changes are a cover for money grubbing adverts to enhance your income. ### 1/5 — Doesn’t update Apple health *2026-08-08, version 5.60.0* Bought this because I saw it connects to Apple health but the fine print says it’s one way. My fault for not reading that closely. But still. How fires this app not push to Apple health yet? What’s the point of bringing all the data into this app ? (Aside from you harvesting it and selling it). That’s literally the entire point of Apple health - to push all data there to keep it centralized. Updated. Cancelled the subscription cause it wasn’t bringing value and it renders the device paid for useless. This company 100% rips you off. ### 1/5 — EKG *2026-08-03, version 5.59.0* Won’t stay connected and won’t read ### 1/5 — Useless *2026-08-01, version 5.59.0* Doesn’t tell you anything you don’t already know and feel by yourself. ### 1/5 — Failure to connect *2026-07-29, version 5.59.0* Logo turned green but wouldn’t initialize. ## Most praised reviews (10 highest-rated) ### 5/5 — Kardia 6L *2026-08-30, version 5.60.0* This is the best mobile EKG device on the market. if you have any kind of arrhythmias, it’s reassuring to have this little device. It has been very helpful with my cardiologist. ### 5/5 — So glad I had Kardia *2026-08-30, version 5.60.0* Approximately 18 months ago I had an episode of tachycardia. My cardiologist did multiple diagnostic tests and concluded that it was not atrial fib. However, he recommended that I get Kardia. I did and would use it occasionally. Last month I became aware of Avery rapid heart rate working my house. I had no pain . I immediately thought of Kardia and used it to record an EKG. Results read something like possible atrial fib. Since the rapid rate continued I elected to go to the ER. I WAS in A fib. If I hadn’t had Kardia I would not have gone to the hospital. I am so glad I have it! ### 5/5 — Good to know *2026-08-29, version 5.60.0* Easy way to track my heart rate. It takes 30 seconds and the info can save your life. ### 5/5 — Convenient and comforting *2026-08-27, version 5.60.0* I had an aFib episode about a year ago (caught by my Apple Watch!) and got a Kardia to keep with me for times when I do not wear the Apple Watch or just want more data and an ECG readout that is pretty much like a doctor’s office. Cheap and reliable insurance especially if you have any rate and/or rhythm issues. Appears to be indestructible as well as it’s in my backpack and has survived so far! Seem to have discounts and deals fairly often as well so look for those. ### 5/5 — Thank you Kardia *2026-08-26, version 5.60.0* Using my Kardia Monitor gives me peace of mind knowing my heart is in normal sinus rhythm ### 5/5 — Excellent Device *2026-08-26, version 5.60.0* I have the 6L and it is superior to the Apple Watch in almost every possible way. The upgrade for additional services through subscription is grossly overpriced and may generate additional revenue, it doesn’t bring that much to the table for the money. Stick with the device and you will be satisfied as well as pleased. ### 5/5 — Peace of mind…z *2026-08-25, version 5.60.0* That is exactly what Kardia gives me…Peace of mind. ### 5/5 — 6 lead *2026-08-24, version 5.60.0* Works well. Recommend for people chasing heart issues. A little hard to use until you get the hang of it. ### 5/5 — Kardia *2026-08-21, version 5.60.0* Love the Kardia always accurate ### 5/5 — Retired *2026-08-21, version 5.60.0* I find Kardia to be useful as it lets me know when I am in Afib and it is recorded for me.
