Generally, most lawyers would say that his authority is limited to the use of tiktok by federal employees or members of the armed forces. Banning the app for everyone at the national level would require more than an executive order.
all five of them. Remove it from app stores, make it illegal to carry and it's toast. If no one in your circle has that app, no point on installing it.
The app stores can fight any such order longer than Trump can remain president.
There is nothing he can do.

He's not wrong.
