During the testing, the heart rate was similar on all three devices. As shown above, the Apple Watch Series 7 is showing 116BPM, Oximeter is showing 115BPM, whereas the Google Fit app is measured the heart rate to be 116BPM. We ran multiple tests, and the results were similar every time, with a maximum variation of 4-6BPM.

We can say that Google Fit’s heart rate monitoring is pretty accurate. But again, it may vary across devices. The device used here is an iPhone 13, which has a very capable camera setup.

You can measure heart rate without enabling the flashlight, but it may impact the reliability of results. If you’re not using a flashlight, ensure you’re in a well-lit environment with enough light to pass through your fingers.

Q. Can You Consider Google Fit Heart Rate for Medical Diagnosis?

No, Google Fit is not that accurate to give you medical-grade heart rate results. You should not rely on it to measure heart rate for medical purposes. Use a Pulse Oximeter, a reliable smartwatch like Apple Watch, or visit a doctor and get your heart rate checked.
