Lately I've been scanning many old family photos and uploading them to my iCloud photo album. I also have many photos in my album that were sent to me by email or text that are missing metadata. It would be nice if I could enter a date and location for these. Also would be great if I could add a caption to some of them, but that is less necessary than the date and location. Is there a simple app that would allow me to edit metadata of photos that are already in my iClould photo album?
