You'd be happy to know there are some great options out there. Adobe recommended a few alternatives in their retirement announcement, including my company, JotForm. To be completely honest, there are several reasons why JotForm is the best alternative, but I'll quickly mention two of them.
1) Automatic, one-step import from FormsCentral. We're the only form builder to offer such an easy way to transfer all existing forms and data.
2) Almost identical feature offering. JotForm even has a new Fillable PDF Form Creator.
Let me know if you have any questions about making the switch! Thanks.

Will I be able to create tillable forms that will be filled out and we will be able to know who is responding to form ui

I'll check on this, but I believe you'll get the same notifications you'd get with the web forms - which usually means if you need to know who your responders are it's good to ask for their contact information (name, email, etc.). Hope this helps!
