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.

The Larmi Watch app is a companion app for smartwatches. Its main functions are as follows: 1. One of the app's main functions is to push incoming calls and SMS/MMS messages from your phone to your connected smartwatch, allowing you to answer and view SMS/MMS messages on your watch. If you reject a call on your watch, you can quickly reply, and the app will send a pre-configured message to the caller. Please note that the app requires "SMS and Call Log permissions" to enable these functions; without these permissions, the app will not function. 2. It records heart rate data collected by the smartwatch and displays it in line and bar graphs. 3. It records exercise data collected by the smartwatch, including steps, cadence, and distance, and displays it in line and bar graphs. 4. It records sleep data collected by the smartwatch and displays it in line and bar graphs. 5. Use your watch to start exercise or fitness activities. 6. Set reminders and alarms for your smartwatch. The data on the app is for reference only and should not be used as a basis for diagnosis or treatment.
