3. I also can offer a simple Notification Extension to send a notification. As you know, App Inventor apps have some restrictions. Which means for the Notification extension: the app must be still running (at least in the background) to be able to send a notification after n seconds.

   The App Inventor Extensions are currently in testing. See the announcement for more information about how to use an App Inventor Extension.
