Below are screen shots from my S Health app taken off the Note 4. If I had updated my weight the measurement would be added to the activity page. I have also included screen shots from the other options available. Whilst S Health does tie you into the Samsung eco system it does work for me.
You can use the app with or without a Samsung wearable. Naturally I am using my Gear S.
I hope Samsung opens the app more to third parties as it has potential but needs to improve as Apple Health kit is leagues ahead. But this app does what I need so I am happy at the moment.

Personally prefer S-health to Apple’s stuff.
I have used S-health on the Note 4 and Galaxy S4 and found it to be really good and accurate in the pedometer and for biking. Good simple widgets as well. Plus it does not require any third party apps like was needed on my Iphone 5S.

I prefer it too. Used it with Note 3, and S5. But having used the Apple Health Kit on a 6 Plus there is no denying that the potential of the Health Kit is huge.
