Web Apps

Web apps are cross platform apps which are used via a browser. This allows you to create a single app to cover platforms such has Windows, Linux, iOS, Android, and so on. These essentially have a server program, which when you start it will allow you to access your app via http://localhost:8000 or http://127.0.0.1:8000. The exact port number may vary, but the server will output the correct link to use.

Database / Models

Models aren't used in Flask, so you will need to use the normal SQLITE queries. Remember the previous tutorials create a class to handle the database, so you will need to write the SQL only. The execute command can be used for Create, Update, Insert, and Delete queries. The select command can be used to run a select query.
