Do you support offline mode?

There is no offline mode available at JotForm yet where you can collect the form submissions without internet access and upload them later to your account.

However, the offline mode is already in our nice to do list, and we have plans to implement it. I have attached an additional feature request ticket to this thread. There is no ETA at this point, but we will let you know if we have any updates.

Note, that there is an Import App which allows you to populate form submissions page with entries from a CSV file.
