You can use another button for save and use tiny db component
And also alist view for viewing it
There a few types of databases that App Inventor offers:

What is the ''point_visible" ?
It is a label or a variable ?
That's the procedure in the prior post that on app initialization loads ListView1's .elements from all the tags in TinyDB1.
