Qaly | ECG Reader

After trying several apps, this one is far above the rest. None of the others came close. The reviews are fast, thorough and have a personal feel.

If you are having any concerns go see a cardiologist— mine told me to never use this app again. An Apple Watch is a 1 lead and cannot tell you your PQRST.

Certainly would give this app a 5 star review but for 3 things. 1) The analysis mistakenly labels the initial heart beat as a OVC. This causes PVCover counting. And many PVC Multiple are actually single. I manually get a rough count by filtering out PVC Single. 2) They have a page on their website that says we can by unlimited human reviews. I think at initial installation I was asked if Zi wanted this but opted for now only for AI reviews. Now I cannot find the option for unlimited human reviews. 3) They continue to not respond to my messages on 1 & 2) even though I sent multiple messages from app and via email. Please note, I have not checked the PVC over read flaw in the latest update. I am still in process of loading 3 years of ECGs one at a time. After zi reinstalled the app, all reviews were lost. It would be nice to be able to quick select multiple ECGs and send to AI for review, even if have to wait a bit for their system to digest them. Thanks, John

Thank you for giving me a direct line of sight into understanding my health data and what symptoms I have been experiencing.

I am an avid ECG taker on my watch and a big fan of self advocacy. I started having heart problems as a teen and was ignored because of my age. With the advent of apple watches I was able to get the proof I needed that I had atrial fibrillation and flutter. My EP knows I’m great at tracking and communicating abnormalities and had even used my ecgs to diagnose SVT when new problems arose after my first ablation. 2 ablations in and unfortunately the afib is back and with several other health issues complicating the situation, I have to watch for new and other abnormalities. Most of the time ChatGPT does a decent job interpreting my ecgs to help me learn to read them and if it’s worthy going to a doc about. (Do not use in replacement of doc and be careful with other models like deepseek who pretends to read. I ran known ecgs to test them and gpt was most accurate) I thought this app could be another tool in my arsenal. However there is a few issues I found. One is cost. You cannot find anywhere how much the interpretations will cost until you’re there. So transparency gets an F. I expected there to be a cost but I also hoped it would at least let you try it before dumping a ton of money. There is no way to test or try it out so I can’t confirm it’ll be any better than ChatGPT or accurate. Second, when you open it, it shows ecgs from your watch. However it seemed to only load about 8 very random ecgs. A few were from last year. Was hoping to look at a reading I had the other day that my watch flagged as afib. Wasn’t one of the chosen few I guess. No way to manually upload it from what I could find. It only walked me through how to turn on permissions, which I clearly had since it was showing some. Third, the questionnaire about heart health: it asks you things like when you were diagnosed with things. This is good. Problem is the most recent year is 2024. So if you were just diagnosed with something, you’ll just have to lie by a year? Given we are halfway through 2025, it makes me question if the app is being updated or maintained anymore. Their website is handy with resources for understanding single lead ecgs but the app itself fell short. And given that the cheaper subscription is not for a human reading it, I really have to wonder if it’s any better than free ChatGPT. I won’t be able to find out as I’m not just handing over a credit card without confirming I’m even getting accurate results with a test report and I wouldn’t have been able to analy

I went through about 8 cardiologists or cardiology NP/PAs who told me I could not have LQTS. Finally, the 9th genetic tested me, and I have the KCNQ1 variant. This appt detected this issue a few years before I was diagnosed. Doctors made me to be crazy for trusting an app for medical advice. In office EKGs were normal but those are a snapshot in time, and are often not conducted during symptoms. My husband and dad’s readings on QALY were normal but my mom’s readings looked similar to mine so I had her tested. She is positive for congenital LQTS as well. QALY was also the first to pick up on my first degree AV Block. My EP applauded this app and told me to use it to monitor my QTc, and head to ER when well into the 500s to get a 12 lead, check electrolytes, and get some magnesium… especially during times of illness/fluid losses. I may owe this app my life! I was started on nadolol and due to the complexity of my other illnesses often requiring qt prolonging meds (like gastroparesis), I may be looking at an ICD.

Only way to communicate is via support email who seems to not exist. I have emailed support over 5 times in 2 weeks to assist in removing my account and data via the option in the app and it fails. No response from support either. This is a scam and if you download and/or signup there is no way to cancel so they have all your data for good. update to developer: yes I was contacting the correct emIl address. I did finally get a response after I wrote this review. I sent several snapshots of the error and finally got another response after around 3 days that my account and data were deleted on the support end. Didn’t solve the app issue but got done what I wanted I guess.

Every ECG I submit from Kardia comes back as unreadable QRS or most of the time it just does not do anything after I press submit

I pay the subscription to have real technician reviews, they get back to you so fast and their reviews of my ECGs help me gain a better understanding of my health. They use language that is easy for me to understand about my health. The AI bit is helpful, but has not been working lately. Besides that, this has been one of the best things I have put my money into. shoutout to the technicians!! ❤️ I highly recommend this app!

VERY helpful app. I have had complex arrhythmias and AFib (which has not recurred after ablation), but the frequency of my ectopic beats was being overcalled by my Apple Watch as afib. Qaly was extremely helpful in providing reassurance that I was NOT experiencing recurrence of paroxysmal afib. Usually the AI bot got it right, but if I was unsure, I’d send to the real person to read. As I experienced more and more ectopic beats, the app (bots & real people who read the tracing) were helpful in documenting atrial bigeminy and atrial tachycardias, ultimately leading to a new anti-arrhythmia drug and successful (nearly complete) resolution of ectopy! It was so nice to be able to get reassurance that I was not having recurrent afib without having to bother the electrophysiology NP/MD, especially in being able to get the answer with a relatively short lag time.
