Hello! I have two questions. When someone is filling out the form, can they save it and finish it up later? Is is smartphone compatible?

Hi,

Yes, this is possible. If you want the users to save their form and continue later, please see this guide on how to accomplish this on your form: How to Save Forms and Continue Later

Plus, this is also compatible on a mobile device. Using JotForm Builder V4, you can now edit your form anywhere and anytime. Please see this blog for more info: Introducing JotForm 4.0 – Build Forms Anywhere, Anytime

Regards.
