I've been looking at Seamless Docs
JotForm has the easiest and fastest user intereface for creating web forms. JotForm has been around since 2006 and it has over 1.5 million users.
We are also providing seamless migration from Adobe FormsCentral. You should give us a try!
JotForm is really no easier than the other suggestions; I tried several of them. I like being able to upload my forms from Adobe Forms Central, okay, but JotForm still not easy for a neophyte like me to navigate, make changes, and figure out how to do things on my forms.. Adobe Forms Central was really intuitive and made everything much easier. I SO wish it would stay!
