August 02, 2025
Update: August 17, 2025 (12:20 AM ET): Google is nowrolling outits camera-based heart-rate and respiratory tracking feature to Pixel phones. While Pixel phones will be the first devices to sport the feature, it will roll out to “more Android devices in the future,” according to Google. Read on for a more detailed explanation of the feature below.
Original article: August 22, 2025 (11:38 AM ET): If you want to measure your heart or respiratory rate, you have a multitude of options. Fitness trackers and smartwatches will usually do the trick, or you can invest in specific medical-grade tools to do the job. For your heart rate, you can even just do anold fashioned pulse measurement.

What if you could do both tests with just your smartphone? That’s whatGoogle thinks would be best. Starting next month, the company is rolling out a Google Fit heart rate measurement tool alongside a similar tool to measure your respiratory rate. Both tools will only require a smartphone to work — no other gear necessary.
Google Fit heart rate and respiratory rate
To measure your heart rate, all you’ll need to do is place your finger over the rear lens of your phone’s camera. We’ve seen this technique used for years through apps on the Play Store. TheSamsung Galaxy S5even touted this as a major feature way back in 2014, albeit with a dedicated heart-rate sensor.
As for the respiratory rate, that’s a bit more complicated. You need to prop up your phone so the camera can record you breathing comfortably for about 30 seconds. Using the footage of your chest movements as you breathe, Google Fit will tell you how many breaths you’re taking. This info can be helpful for discovering health issues or supplying it to your doctor.

Google claims it took great pains to verify the respiratory test will work for everyone, regardless of your body shape, age, or skin tone.
As usual, neither the Google Fit heart rate test nor the respiratory test should be used as a proper medical diagnosis. You will need to consult a licensed physician for anything official.
These new tests will only work in the Google Fit app on Pixel devices at first. Access to the tests will land next month, likely alongside the expectedPixel feature drop, the first for 2021. Google says the tests will work on other phones in the future.
