You may track steps using your iPhone or Android mobile phone.
Most mobile phones are able to track your steps automatically, but there are some minimum requirements for this feature to work.
Android Devices:
Samsung phones are capable of tracking a user's steps through the app S Health with OS Android 5.0 Kit Kat or higher.
Non-Samsung phones are capable of tracking a user's steps through the app Google Fit. Google Fit can be downloaded for free from the Play Store.
iPhone Devices:
Your iOS system must be updated to version 15 or higher.
Older versions of the iOS are not capable of tracking steps even with the Health app installed.
