This is one of the most productive tools I have used in a long time. Making forms is easy; editing is easy and distributing the form is even easier.
Been a user for a couple of years, since it first went into beta - loved it then and still do. So many possible uses, beyond simple forms.
Been using Paperform for over a year with good results. Respondents liked the design and clarity in form formats. Responsive anywhere it appeared.
It has been an evolving product. I remembered 15 months or so ago it just introduced conditional logic, now it has almost every control features.
I still wish it has direct integration with Google Sheet and other popular services, though. Zapier and webhooks are both good and I'm using them, but it is costly and/or I have to touch the code.
