1. Fer's answer works perfectly without the danger of renaming the apps. Perhaps it was misunderstood by some. The easiest way to do this is to open Terminal, type ln -s (included trailing space) and drag the App to be 'renamed' into the Terminal window twice. You should have the full path to the app in your command twice, modify the second path to rename the app, just keep the path the same.
2. Follow these steps: To open the Terminal, go to Applications Utilities. Double-click on the Terminal application. The Command Line will now have been opened. To start renaming files, type the command following this format: mv.
3. In the Shortcuts app, do one of the following: In My Shortcuts, tap on the shortcut to open the shortcut editor, tap to open Details, tap the name row, tap, type a new name, then tap Done. Touch and hold a shortcut in My Shortcuts, tap Rename, tap, type a new name, then tap OK.
