Earlier this year, the Google Fit application received support for a new feature that enabled Android smartphones to monitor the heart rate and the respiratory rate on the device. Now, it has been confirmed that the feature is available for iOS as well.
The Google Fit application on iOS for iPhone will now be able to record the user’s heart rate along with the respiratory rate, reports 9to5Google. The feature will also work when the smartphone doesn’t have an active internet connection.
For this feature to work, the device’s camera is used. When users place their finger on the rear camera sensor of the device and apply slight pressure, Google fit can track the incoming light in the sensor to gauge the heart rate.
Users can also place their hand in front of a light source and allow Google Fit to measure their heartbeat by tracking what the company says are subtle changes in the color of the user’s fingers. It takes about 30 seconds to show users a graph with beats per minute.
After the results are shown on the screen, users also have an option to save the vitals. Google claims that the accuracy of the process is determined by algorithms that also account for factors like age and skin tone, among others.
The feature was first introduced in February this year but was initially limited to the Pixel lineup of smartphones and gradually the company added support for more devices. Now with support for iOS devices, it has expanded to more devices.
