Last year Xiaomi introduced a new MIUI shell system application called MIUI Health. This application offers a number of functions such as step tracking, running, cycling and climbing stairs, monitoring the quality and duration of sleep, and tracking the menstrual cycle.
A new version of the MIUI Health application has now been released, version number 2.7.4, which has a new heart rate monitoring function. A few years ago, Samsung included heart rate sensors in its flagship smartphones. But with the advent of fitness trackers and smart watches on the market, the company has abandoned this practice. Another reason – it saves space inside the body of the smartphone for other components.
At the same time, Xiaomi has implemented heart rate monitoring in its MIUI Health application without relying on a special sensor. The application uses a phone camera and an LED flash to measure the heart rate.
The heart rate monitoring function was confirmed in the Telegram channel called @MiuiSystemUpdates. From the description provided by the channel, users need to cover their phone’s camera and LED flash with one finger until the progress bar fills up. Then you need to select your current status: “Normal”, “Quiet” and “After Training”. As with the Mi Fit application, users will have access to their heart rate measurement history. It is not yet known how accurate the data obtained in this way are.
The MIUI Health application was originally limited to the Chinese version of MIUI 12 . But now it is also available in other regional software assemblies for Xiaomi and Redmi smartphones.
