Hi HomeKitAppleHome,
Welcome to Apple Support Communities. We understand that you're interested in having a Health widget available for your iPhone. We'd like to help.
While it doesn't appear that Health is an option, you could add a Fitness Widget to your screen. This would quickly show your progress of your Move, Exercise, and Stand rings. Then, you can click on the widget to bring you to the Fitness app, where you can see your steps right when you open it: How to add and edit widgets on your iPhone
If that doesn't work for you, it may be helpful to leave feedback here: Product Feedback
Hope that helps.
Cheers.
