OK. some limitations, like I need conditional logic, so if someone checks the Yes box for a question, then require them to fill out other fields. Need this conditional logic functionality, critical for my application. Else not sure PDFFiller will be useful to us.

If you have a lot of digital documents, you should use pdfFiller My overall experience is great! It's free and very easy to use, and I strongly recommend it for any student, teachers or professors, colleagues from work, and even for managers because during this pandemics, we all had to adapt our documents to digital format, and print them at home could be an issue for many people. I love to use this software because it's free and it allows me to sign digital documents from anyone in my company without having to print everything, sign it all, and then scan it, and e-mail it to the recipients. It's great because it has other checkmarks so you can add little details in case you are reading a contract or a file that needs reviewing. Positively, there are no cons for this software, as I have been using it for work and college matters, and it solves a great deal of signing important documents!
