Google Fit for iOS can now measure heart and respiratory rate using the device’s camera: report


Google Fit for iOS is said to have acquired the ability to track and measure heart and respiratory rates using an iPhone’s camera. The fitness app can measure a user’s heart rate when they apply light pressure to the rear camera lens. It can also work if the user’s smartphone does not have an active internet connection. The front camera, on the other hand, tracks a user’s breaths per minute (BPM). Google Fit’s heart and respiratory rate tracking feature was first introduced for Google Pixel smartphones in February.

9to5Google reported that Google Fit on iOS is receiving heart rate and respiratory rate measurement functionality. Google tracks the subtle movements of a user’s body to measure their heart rate and BPM.

Google Fit measures a user’s heart rate when they place a finger on the rear camera sensor and apply light pressure. If a user is in a low-light environment, the fitness tracker app can use the smartphone’s flash to increase accuracy. Alternatively, users can place their hand and their iPhone phone in front of a light source. Google measures heart rate by tracking “subtle changes in the color of your fingers” to assess blood flow. Heart rate algorithms also take into account lighting, skin tone, age, and other similar factors.

The heart rate measurement takes approximately 30 seconds and displays a graph with beats per minute (BPM). Once the process is completed, the user has the choice to save the vital data in Google Fit.

Also with Google Fit for iOS, an iPhone’s selfie camera can track a user’s respiratory rate by tracking their breathing per second. For this to work, users need to keep their phone steady and steady with their head and torso clearly visible on the app screen. On-screen prompts guide the user to stay still for approximately half a minute. Subtle chest movements with computer vision that follow tiny physical movements measure the user’s respiratory rate.

Alternatively, measurements on Google FIt can also be started by going to the Browse tab and clicking on Vitals. Users also have the option to set reminders for measurements.

9to5Google mentioned that they can view the new heart and respiratory rate readings on iPhone 7 and iPad Pro. The report also says that if users recently downloaded Google Fit and it doesn’t show the new maps, closing the app from the multitasking screen and reopening should make it work.

Google first introduced heart rate and respiratory rate measurement functionality for Google Fit in February. Features were originally released for Pixel smartphones, eventually reaching other Android smartphones.
