@barbb. If you are only tracking steps/miles you walk, your Apple phone probably have those features. I use Google Fit bc I have an Android phone. As far as tracking sleep, I take my fitbit results with a grain of salt. People can get too stressed out with the numbers and it defeats the purpose.. . If I get up feeling rested, that's the important part. I still wear it knowing that it may not always be 100% correct. My friend has both the Fitbit Versa and the Oura Ring fitness tracker, and the numbers don't match at all....
