Change date on photos on iPhone

The Photos.app on the iPhone does not have a tool to change the capture date of a photo. There are some extensions from the AppStore thata llow you to change the date. I have not tested them.

I am simply changing the dates on my Mac, and sync the changed photos to my iPhone with iCloud Photos.
