To make it work (slightly technical, but easily doable), you must make a copy of the Form I made. Just follow the instructions on my site. If you accidentally use my form without copying it, your data will go to my account. If you change the Form without copying it, you will change my Form. Any data you find in my form is fictitious, and is created only as a means to test it.
Once you have the copy made, you then add it to the app. The app will remember it, and will open your Google Form when you open the app. It will remember the page you entered. If you submit an empty box, it will clear that memory and you'll have to resubmit your form. Once you complete the form, the data is accessible from your Drive account. This app simply eliminates a step to open the Google Form. The work was not done creating the app, but in developing the Google Form
