What It Is

HeartScan is an online heart-rate detection tool. Users simply open the webpage in a mobile browser, place the phone on their chest, and keep still to get a heart-rate reading in about 10 seconds. It emphasizes that no wearable device, registration, or app installation is required, and that it does not use the camera or flash.

Core Capabilities and Technology

The product’s core approach is not traditional camera-based PPG measurement. Instead, it uses the phone’s motion sensors/accelerometer to capture tiny chest vibrations caused by the heartbeat — a technique known as SCG (seismocardiography). The page says this technology originated from early human spaceflight missions, and also mentions that SCG has shown better sensitivity than exercise ECG for detecting coronary artery disease in independent research. However, based on the available text, HeartScan currently clearly offers heart-rate measurement; whether it provides disease diagnosis, AI model analysis, or clinical decision support is not sufficiently explained.

Pricing and Access Requirements

The page repeatedly labels the service as a “Free Online Tool,” with prompts such as “Start Free Pulse Check” and “Free in 10 Seconds,” so its basic online check appears to be free and does not require registration. The main text does not disclose any paid plan, subscription, enterprise/clinical package, payment method, or usage limit.

Strengths and Limitations

Its strengths are a very short user flow and browser-based measurement; it does not call the camera or flash, making it more privacy-friendly for sensitive users; and it does not depend on hardware such as a smartwatch or chest strap. The page also claims HIPAA compliance, clinical testing, and over 100,000 users.

The limitations are mainly around insufficient disclosure of key information: it does not provide a heart-rate error range, supported phone models, sensor requirements, the impact of abnormal posture, whether data is uploaded or stored, or what encryption methods are used. Its clinical testing and research references also lack full verification details in the main page text, so its results should not be treated as equivalent to a medical diagnosis.

Who It’s For and Access from China

HeartScan is suitable for general users who want to quickly check resting heart rate, do not have a wearable device, and want to try SCG measurement at low cost. It may also be useful for healthcare and wellness professionals who want to understand this type of technology. The main text does not state whether the service is accessible from mainland China, so network availability is unknown; payment information is also not disclosed. If it is unavailable, alternatives include Apple Watch, Fitbit, Samsung Health, Google Fit, camera-based heart-rate apps, or professional medical-grade ECG/heart-rate devices.
