Google introduced the feature to track critical vitals directly on your Android device at the beginning of this year. Now, Google Fit offers the same feature on iPhones; it can assess your heart and respiratory rate with simply your iPhone’s camera. What you need to do is, you have to put your finger on the rear-finger camera lens and apply light pressure, in order to begin measuring your heart rate. In case you want to check your vitals in low light condition, you can use the flash to increase accuracy.

Google Fit details
To estimate blood flow, Google will track subtle variations in the color of your fingertips alongside using heart rate algorithms accounting for lighting, skin tone, age, and other factors. It also works without the need for an internet connection. What’s more, the measurements will take roughly 30 seconds. The results will be shown with a preview graph and BPM listed at the bottom of the screen. You can then choose whether or not to save the vitals to Fit.
In the meantime, the front-facing camera will count how many breaths you take every minute. It is important to note that Google Fit uses machine vision to track the smallest physical signals at a pixel level. With the help of that, it calculates your breathing rate based on modest chest movements. Google unveiled this option for Android phones in February. A month later, it started rolling out to Pixel phones, and then it expanded to other devices. In Google Fit’s iOS Home feed, we recently observed cards advertising “Check your heart rate” and “Track your respiratory rate.” Even in support papers, Google has failed to mention the camera heart/respiratory functionality for iPhone, which was last updated in late November.
