Welcome to the community, @Elio_Lombardi!
Where is your data coming from and how is your app consuming it? To @WidleStudioLLP's point, Retool works best when your data is stored in an external database and queryable via either a direct connection or API call. That way, you can have one static app that simply fetches the most current data when it's booted up.
If the timing works, I'd be happy to answer any additional questions and help you out during our scheduled Office Hours!
