Because of Qaly, I went to my doctor and was diagnosed with SVT and was told it was probably never an anxiety disorder. I have lived 15 years of hell thinking I was having intermittent panic attacks and agoraphobia. Getting set up for an ablation. I will be forever grateful.” — Marcie D. from Alabama “Qaly was so helpful in quickly identifying signs of a potentially serious heart condition … Without Qaly, I would have blown off the ECG and maybe shown it to my primary care doctor at my next appointment a few months away.” — Lori B. from Virginia “My Apple Watch categorizes my arrhythmia as normal or inconclusive, which makes me question what I’m feeling. Without Qaly, it would’ve taken me another 6 months to a year to take this to a doctor. With Qaly I gained valuable information. Qaly is the key.” — Jessi I. from Washington ----- Qaly members get peace of mind: • ECG analyzer for all watches and devices: Apple Watch ECG, Fitbit ECG, Kardia ECG, Wellue ECG, Withings ECG, WHOOP ECG, Garmin ECG, holter monitors, and more. • Borderline ECG, Inconclusive Apple Watch ECG, Inconclusive Fitbit ECG, Unclassified KardiaMobile EKG, WHOOP ECG, Garmin ECG, and all other Inconclusive ECGs analyzed within minutes, for clarity. • See irregular heartbeats like PAC and PVC on your ECG, analyzed by an expert ECG reader. • See your PR Interval, QRS Interval, and QTc Interval on your ECG, also analyzed by an expert EKG reader. • Get more from Qaly technician interpretations than your typical ECG analyzer app or HRV tracker: Qaly is the only ECG interpretation app where human experts provide professional analysis of your heart readings within minutes. • Share Qaly reports with your doctor, cardiologist, or electrophysiologist. ---- The Qaly app displays ECG data by integrating with the Health app. This is not available on the iPad.

ECG Wizard: Innovative Features Unveiled 1. Accurate Heart Age Estimation The app's primary feature is its ability to use AI technology to accurately estimate the user's heart age based on ECG data collected from Apple Watch. Heart age is defined as the age of your heart's health compared to your actual age, serving as a crucial indicator for users to understand their heart health more intuitively. By leveraging AI's deep learning and data analysis capabilities, the app can precisely predict whether your heart is younger or older than your actual age. 2. Cardiovascular Disease Risk Prediction Another standout feature is the app's ability to assess the user's risk of cardiovascular disease. By analyzing ECG waveform, rhythm, and other critical indicators, combined with factors such as lifestyle and family history, the app's AI model can predict the level of future cardiovascular disease risk. This provides users with vital early warnings, enabling them to adjust their lifestyle and seek professional medical advice to prevent cardiovascular diseases. 3. Mortality Risk Assessment One of the most groundbreaking features is the app's capability to evaluate the user's mortality risk. While this might sound alarming, the feature is achieved through in-depth analysis of ECG data and various factors directly related to heart health. The AI algorithm identifies high-risk cardiac conditions, such as arrhythmia and cardiac hypertrophy, which could increase the likelihood of sudden cardiac events, posing a threat to long-term health. By integrating advanced AI technology with the ECG functionality of Apple Watch, this app pioneers a new chapter in personal health monitoring. It provides real-time, accurate assessments of heart health, helps users predict cardiovascular disease risks, and take preventive measures, greatly enhancing quality and safety of life. As this technology continues to evolve, humanity's understanding and control over personal health will become unprecedentedly precise and efficient. Note: The "AI ECG Diagnosis" feature is not a substitute for professional medical diagnosis. The AI ECG results provided by this product are for reference only. Users must consult a qualified physician to interpret or act on the information output by the device for clinical decisions. The AI ECG diagnosis is intended to assist users in evaluating their health status for early detection of potential issues and is not meant to replace traditional diagnostic or treatment methods.
