What is JotForm?
JotForm is a free online form builder which helps you create online forms without writing a single line of code. No sign-up required.
At JotForm, we want to make sure that you’re getting the online form builder help that you need. Our friendly customer support team is available 24/7.
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 am afraid we don't have such feature as of this moment. The limitations we have right now is you can set an expiration date for your form. But for your requirement to have a timer while the user answer the form, is not available right now.
I will try to submit this to our nice-to-do list and hopefully our developers will implement this if a number of users request for this feature.
Thank you for using JotForm.
