Use tinydb to check the status of screen… and check the value , it is simple
If form closed, save tinydb tag-form value-closed
If again closed, save tinydb-again value-closed
When screen1 intitialise,
if get value tinydb tag-form and tinydb tag-again is not equal to memory string,
Then call noticias alert = You have already submitted and
Call clock timer enabed to true
Else (you design it further)
If clock 1 timer
Call clock1 time enabled to false
Close the application
Since your google form is only one page you can detect url change .For example form’s url ends with https://.../viewform and when submitted the url ends with https://.../formResponse so you do not need so many clocks. If not submitted next time app opens at same page , if sumbitted - detect url change and save to tiny db - direct to site
