I was on a very long quest to find the perfect HTML form designer, trying two other AppSumo offerings and a few others before finally settling on Form Designer. My need is for a straightforward and not-too-technical tool to design and deploy online forms for some of the websites of my clients. These sites have been "flattened" (i.e. converted from WordPress into static websites) and I needed something that didn't require me to write code and offered enough functionality to work properly in a variety of situations.

So far, any technical assistance I've required has been responded to in less than a day and the help has been informed and correct. The product has a reasonable amount of documentation and the interface is relative intuitively and functions as expected.

The AppSumo deal isn't overwhelmingly generous - it basically runs out once 1,000 forms have been submitted. However, the ongoing pay-as-you-go rate of 8 to 15 cents per form is reasonable, as is $10.44/month for up to 20,000 submissions for high-volume users.

Online form design software needs to serve many masters with many varied needs and it's seldom that one product will fit every use case. However, I think that Form Designer will satisfy most users' needs.
