Tapping on the Share icon gives you a menu of options that vary depending on what app you are in. For example, if you are in Safari you will have options to bookmark a webpage, add it to your reading list, send it to a friend and more, while pulling up the share sheet in Photos will give you some different options like create a watch face or add to a slide show. iOS 13 has overhauled the Share menu (or Action menu), adding a list of options beneath the two familiar horizontal rows.
