Qaly gave me back some control letting me know what my weird beats were, stating if they were within a normal range and giving me some much needed information about my heart. Peace of mind obtained.
This app helps me differ when a flutter in my chest is something more serious or just a flutter I don't need to be scared about.
No waiting for an appointment and hoping the thing you came to check out occurs in the doctor's office.
Available 24/7
Every recording is measured in seconds, then read by a certified cardiographic technician. Here is what comes back.
More than 30 rhythms and findings, each graded from normal through to needing immediate attention.
PR, QRS and QTc measured on every recording and flagged when one sits outside the usual range.
Every extra beat marked where it happened, PVC or PAC, with your heart rate and heart rate variability.
A certified cardiographic technician reads the same recording, confirms the numbers, and writes back in plain words. Their name is on every review.

WellueYour heart can change from day to day. Qaly keeps your ECGs and heart measurements together, so you can see how things change over time.
An example
PR is how long the signal takes to cross your heart, top to bottom. Twelve monthly readings from one member, each unremarkable on its own. Together they show it creeping past the usual range, and that is what a technician caught.

For your appointment
Ten minutes with a cardiologist is not long enough to describe a year of palpitations. Export any period as a PDF and hand over the whole record instead.
“Next time I showed the Dr the QALY interpretation and they took me seriously.”
With the modern availability of at-home devices that can measure ECGs, it is now challenging for cardiologists to keep up with all of these readings. On Qaly, trained ECG technicians read every ECG you submit. If you want to learn what your ECG may be telling you, this is the place to start.

Don’t take our words for it. These are members who sent an Apple Watch, Fitbit or Kardia ECG when they felt palpitations, saw AFib flagged, or got no answer at all.
During a recent hospital stay for monitoring of new Tikosyn medication I used Qaly to read an ECG I did on my Apple Watch. The nurse was impressed with the Qaly results, specifically with the QTc values since the Tikosyn directly impacts that.
Excellent app. Helped read my diagnosis during an episode of SVT on my Kardia device. Friendly customer service.
My fitbit ecg said normal sinus rhythm but the tracing looked odd and i felt jittery. I signed up and sent the report. A few minutes later i received a reply explaining that, even tho it looked a little weird, all of the important info indicated normal sinus rhythm and i was fine. I cannot describe the relief.
Fantastic use of AI with additional benefit of human review. I love that I can pinpoint strange rhythms I'm feeling, flag them with symptoms, and show them to my doctor — but also avoid unnecessary trips to the ER.
I was sitting up late one night worrying about my heart rhythm. I downloaded the app, signed up, and uploaded an ECG taken from my Galaxy Watch. Within 5 minutes I received knowledgeable, friendly, and reassuring professional feedback.
On the Qaly app, certified cardiographic technicians read your ECG.
Cardiographic technicians are health professionals — like cardiac nurses — who study how to read abnormal heart rhythms from ECGs in hospitals. These cardiographic technicians are trained to identify irregularities like SVT, AFib, PVCs, PACs, Short PR Interval, Inconclusive ECGs, and more.
Now, on the Qaly app, these same technicians read ECGs from your smartwatch or at-home ECG device, 24/7, whenever you need them to.
Most importantly, all cardiographic technicians on Qaly have successfully cleared the CCT exam administered by Cardiovascular Credentialing International, which is considered the gold-standard in heart rhythm analysis credentialing for cardiographic technicians.
On the Qaly app, certified cardiographic technicians monitor your ECGs for 33 different abnormal heart rhythms, or arrhythmias:
• Complete Heart Block
• Ventricular Tachycardia (Sustained)
• Second Degree AV Block Type 2
• Sinus Pause >3 Seconds
• Ventricular Tachycardia (Non-Sustained)
• Sinus Pause <3 Seconds
• Atrial Fibrillation
• Atrial Flutter
• Supraventricular Tachycardia (Sustained)
• 2:1 AV Block
• Accelerated Idioventricular Rhythm
• Supraventricular Tachycardia (Non-Sustained)
• Wenckebach
• Wolff-Parkinson-White Syndrome
• Ventricular Bigeminy
• Ventricular Trigeminy
• Atrial Bigeminy
• Atrial Trigeminy
• Junctional Rhythm
• Premature Ventricular Contraction (Couplet)
• Premature Atrial Contraction (Couplet)
• Premature Ventricular Contraction (Multiple)
• Premature Atrial Contraction (Multiple)
• Premature Ventricular Contraction (Single)
• Premature Atrial Contraction (Single)
• Premature Junctional Contraction
• Ectopic Atrial Rhythm
• First Degree AV Block

Extremely grateful for the person who reviewed my ECG.
To the pros reading my ECGs, thank you!
Life changing!
I looked for an app that uses real technicians, and not an algorithm to read my ECGs. Luckily, Qaly was there at the right time for me.
