Heart rate comparison between Apple Watch and Google Fit

Since Apple Watch also has the function of measuring heart rate, I compared it with Google Fit data to try to find the difference between the two:

7:00 PM:

  • Google Fit: 65 BPM


  • Apple Watch: 67 BPM

6:56 am:

  • Google Fit: 72 BPM


  • Apple Watch: 72 BPM

9:42 am:

  • Google Fit: 70 BPM


  • Apple Watch: 73 BPM

2:04 PM:

  • Google Fit: 72 BPM


  • Apple Watch: 72 BPM


I can't tell if the Google Fit or Apple Watch heart rate data is more accurate.But the above data is enough to show that the difference in readings obtained by expensive dedicated wearables and free apps that use the iPhone's camera is almost negligible.
