JotForm is a free online form builder which helps you create online forms without writing a single line of code. No sign-up required.
We believe that if one user has a question, there could be more users who may have the same question. This is why many of our support forum threads are public and available to be searched and viewed. If you’d like help immediately, feel free to search for a similar question, or submit your question or concern.
I would like to inform you that we do have a way to allow users to fill the form offline. That is by creating a Fillable PDF version of the form. By creating a Fillable PDF version, the user can fill in the PDF form and save it to their device while offline, and once they have an internet connection, they can submit the PDF form. Please follow this guide on How to Create a PDF Form.
For more information about the Fillable PDF, you can also check out this guide: Fillable PDF - Everything you need to know about JotForm Fillable PDF Creator.
If you mean you want to be able to view the submissions offline, then you can choose to download your submissions as PDF, Excel or CSV format. This will serve as your backup and would allow you to view the submissions even without an internet connection. Please follow this guide on How to Download Form Submissions as Excel/CSV/PDF?
If this does not fit your requirement, please let us know so we can better assist you.
