Jotform

All forms are mobile responsive and a mobile app for Jotform can be downloaded on your phone. Forms can even be created on the mobile app. The desktop and mobile are similar. Choose from many themes and templates., choose from classic form and card form.
Form fields are less restrictive. Manipulate forms by drag and drop. Widgets can be added to forms for e-signatures and check lists. Image slide is another choice. Forms can be automated and decrease workload. JotForm advises on how to get better response rates from your forms.

I spend a lot longer than I want using JotForm. It takes a long time to find the right template, the right theme, and personalize them. The freemium plan is restrictive. The customer support team did not answer my questions or solve my problem. I had to ask another JotForm user how to even reach them because JotForm is unorganized.

It appears, on the surface, to offer a ton of really nice form elements & features. You can make the forms do a lot of seemingly cool stuff that's difficult, if not impossible in some other form builders (until you actually deploy them & discover their true, undisclosed limitations/quirks).

There are constant bugs, quirks, and downtime, with ZERO live support regardless of subscriptions level. My biggest issue is with prefilling forms for customers. Important fields like the product list can't be prefilled so all the customer has to do is review & sign. Of course, it doesn't tell you this until you go to actually prefill a form. Now I'm left with a situation where I have to have a different, less-capable form if I want to prefill contracts for customers using existing info. What a waste. Better yet, there's no support. If you have a question or issue, you get to wait for an email response. Of course, they only deal with part of what you've asked, so you then have to send another email, then wait another unknowable period of time for the next person to deal with half of the problem, then requiring another email, another wait.... and so forth. Of course, if it's an underlying issue with their software (like the improperly functioning dropdown quantity selector), they say they'll send it to the developer team, and who knows when/if the problem will get addressed at that point. They literally tell you that they can't tell you. Not acceptable for commercial deployment, imo.
