What do you do once you have designed your application

Hello tmo3000,

I am not sure if I have understood your question correctly? Do you mean to say what to do next after you have designed your form? 

Please note that once you complete working your form, you can start using it by accessing it from your form's direct URL. Please check the screenshot below how to access your form's direct URL:  

Please note that you can also embed your form in any webpage. You may like to take a look at the following guides on how to embed your form in webpage:
