On the other hand, the rear camera will be able to recognise subtle color changes in the skin when your fingertip is held over the lens, thus offering a pulse reading. As per updates from Google, the algorithm is accurate within 2% based on the company’s testing.

Interestingly, the users will be able to take these heart and respiratory readings in the Google Fit app. As far as privacy is concerned, these readings will not be saved anywhere. Only the final measurement is added to the Google Fit dashboard.

However, Google isn’t the first company to start smartphone cameras for health measurements. Amazon’s Halo activity tracker and wellness service have earlier added BMI readings through your phone’s front-facing camera. However, using this feature requires owning the physical Amazon Halo band.

Notably, this new feature from Google will make the Pixel’s already-great camera even more capable when it goes live next month. Google is also working on bringing these new fitness tools to the app on out-of-brand smartphones, in the near future.
