Drag-n-drop layout allows you to create web forms with a few clicks only and publish them on your web-site immediately.
Great form creator.
Pros: When web programming I find myself heavily focused on using PHP web language. Having a dedicated form creator and an amazing offering.
Cons: This is not really a con as most software lacks an offline solution. Though I find this to be a major problem as you don't have fast internet access from everywhere .
Overall: Great solution for on the web form creation.
