can an iphone 5 count steps and walking using the Health app without another app being involved?

I tried to set Health up on my iphone 5 to provide walking distances and count steps. I cannot find a way of doing so because I cannot set my phone as a source. My wife has this all set on her 5S. Is there a design difference between the phone models that prevents this feature from working on the 5? If not, how do I set my phone as a source. The 5S is set as a source by using settings/privacy/motion and fitness which although using the same software as my 5 (iOS 8.4.1) does not exist in the 5 settings/privacy menu.
