Google Fit on iOS uses a camera for heart rate measurement

The Google Fit application on the iPhone can measure the heart rate and frequency of breaths using only a smartphone camera.

At the beginning of this year, Google introduced the ability to track key indicators directly on an Android device.Google Fit on the iPhone has now received the same possibility of measuring the heart rate and frequency of breaths using the camera itself.

Heart rate measurements start with applying the finger to the camera lens directed backwards and light pressure.It is possible to turn on the flash to increase measurement accuracy in a dark environment or place your hands (and phone) in front of the light source.

Google tracks "subtle changes in the color of the fingers" to present blood flow, and heart rate algorithms take into account lighting, skin tone, age and other factors.In addition, the function works offline without having to connect to the Internet.The measurement takes about 30 seconds with a chart preview and BPM recorded at the bottom of the screen.After completing, you can decide whether to save the data in the FIT application.

Meanwhile, the front camera is used to track the number of breaths per minute.Just put the phone on a stable surface so that the head and upper part of the torso are captured.Users are then led by a process with "hold breath" for half a minute.Google Fit calculates the frequency of breaths based on subtle chest movements, and the computer vision follows small physical signals at the pixel level.

In February, Google announced this function for Android phones.It began to appear on Pixel phones and later also on other devices.Cards with the inscriptions "Check the heart rate" has now appeared in Google Fit on iOS.The FIT application has recently been updated at the end of November, but to this day Google has not yet officially confirmed the introduction of heart rate and saturation function using the iPhone camera, even in the assistance documents.

Measurements can also be initiated by going to the Browse ➔ health tab and scrolling down to the prompts.Users can set alerts that will remind you to make measurements from time to time.If you just installed the app and you don't find new cards, close the fit application completely and open it again.
