Google has recently updated its Google Fit app for iOS devices in which it can now measure your heart rate using your iPhone’s camera. How this is done is users place their finger on their iPhone’s camera and apply some light pressure to it, and from there, the app will attempt to read the changes in the color of your fingers to determine your heart rate.
It will take about 30 seconds for it to read your heart rate, after which the results will be shown at the bottom of the screen. Google had previously introduced a similar feature to its Android app, so it looks like it has finally made its way onto the iPhone as well. That being said, this feature is more akin to capturing your heart rate in the moment, as opposed to wearables that can provide users with continuous tracking.
However, it could be handy if you’re not feeling well and want to see if there could be something wrong. Google does note that the feature isn’t meant to be used as a diagnosis tool, but like we said, it could be useful if you feel that something isn’t quite right with yourself and you want to bring these results to your doctor for further consultation.
