How to continue formatting a form in mobile mode?

I have a form already built in normal mode and want to be able to use the features in mobile mode and reformate. Is there a way to do this automatically?

Yes, once you have started creating a form in the normal mode, when you open the form using JotForm mobile forms, you can continue formatting and creating the same form in your mobile app itself.

Once your account gets synced in the mobile app, all created forms will be visible in your main page. 

For example, I created a form "test 3" in normal mode and then later wanted to continue using the mobile app. When I opened my JotForm Mobile app, once the forms got synced, I could see them in my main page. Just select the required form and you can continue editing your form, where you left off. See the screenshot below.

Hope this helps.
