脉安 - 健康助手：指尖秒测心率，您的全方位智能健康管家

脉安 measures heart rate using two methods. It detects heart rate via a fingertip on the phone camera or by precisely capturing facial blood flow signals with the camera during a 30-second face scan.

No, 脉安 does not require additional hardware devices for health monitoring. It uses the smartphone's camera for all measurements, including heart rate, tongue diagnosis, and face scan health detection.

脉安 provides six key vital sign data points through face scanning. These include heart rate, respiratory frequency, and stress index. The health detection completes in just 30 seconds.

No, 脉安 is not a medical diagnostic device. It functions as a tool for daily health trend tracking. The app does not provide medical diagnoses.

脉安 ensures data security by encrypting blood flow feature information during transmission. Measurement history is stored with bank-grade encryption. Face video images are processed in memory and are not saved.

Yes, 脉安 analyzes tongue images for health insights. Users photograph their tongue, and the system uses machine learning algorithms to identify features like tongue quality and coating, generating a health report.

The 脉安 dashboard displays key health indicators like heart rate, HRV, and BMI. It also integrates daily exercise data, including steps, walking distance, and calorie consumption, for a comprehensive overview.

Yes, the 脉安 subscription is an auto-renewing service. It automatically renews at the end of each subscription period, and the associated fee deducts from your iTunes account.

You can cancel your 脉安 subscription at any time. To do this, disable auto-renewal in your iTunes account settings at least 24 hours before the current subscription period concludes.

TOI™ stands for Blood Spectrum Optical Imaging, a patented technology used in 脉安. This technology precisely extracts blood flow data from facial signals, which the DeepAffex™ AI engine then analyzes.
