On Pixel devices, Google Fit can detect heart rate and breathing rate via the camera sensor. The feature, though, is now rumoured to be coming to iOS devices. According to a new claim from 9to5Google, Google Fit is now bringing the same capabilities to iOS, allowing iPhone users to take advantage of the service.
iPhone owners will be able to measure heart rate and respiration rate via the device’s rear camera as a result of the update. When the smartphone does not have an active internet connection, the feature will still work.
How does it work?
Google Fit can detect the incoming light in the sensor to determine the heart rate when users place their finger on the device’s rear camera sensor and apply slight pressure. Users can also position their hand in front of a light source and use Google Fit to track “subtle variations in the colour of your fingers” to measure their heartbeat.
The process takes about 30 seconds and results in a graph with beats per minute for users to see. Users can choose whether or not to save their vitals to Google Fit after taking measurements. The process’ accuracy is established by Google Fit’s algorithms, which take into account characteristics such as age and skin tone.
When it comes to the respiratory rate measuring feature, it works by detecting a user’s breath while holding the phone stationary in front of them and displaying the torso in the app’s display. When users need to hold still, the app’s on-screen prompts will guide them. When you breathe, your small chest movements will be noticed, and the app will keep track of your breath rate.
