Great until I realized I couldn't use one form to save in different ways. I had to go back and delete and rewrite for each person I was filling the form out for.

The site is very easy to navigate. I'm a novice when it comes to anything to do with forms, etc. Your site is so easy because it's intuitive. It just makes sense about what to do next, no hunting around trying to figure what the site builders were thinking. Easy peasy.

Like any software you need to learn the program and the first time I used it I was struggling and reached out to support. I was AMAZED at the quick response I received and the step by step instruction.
Lori S
The Support is Supherb!! They are right there when you need them! As a new comer, I expect I will need them a lot. Give special thanks to Ryan. I am enjoying this!

Pauline really helped me out a lot Pauline really helped me out a lot. She answered all my questions and she was very patient with me. Overall she’s a great working.

Don't quite understand how it works as I am not a computer person except to do genealogy, and write. One cannot operate a computer without it. At least this is what I'm finding out. It all seems automatic, I would like to know more about it's function, Why's and what-fores, instead of just logging on and it appears. All I know is that it is a major function for downloading photographs and some documents. There should be a tutorial offered to those who are senior citizens and so many things are automatic. It takes understanding its function to a non-software-computer person. Guess more instruction would help.

What do you like best? The ease of use, the verification of signature and the compatibility on all types of documents What do you dislike? The cost...yearly is pricey considering there are programs that you pay more upfront but it’s a one time fee What problems are you solving with the product? What benefits have you realized? Making my documents fillable for my students while teaching remotely
User in Primary/Secondary Education
What do you like best? I love how easy it is to navigate. the User-functionality makes it very easy to use and know how to create new content. What do you dislike? I wish there was a more user friendly version in IOS or Android App Store. Recommendations to others considering the product: There is so much this Program can do. If you have the time, watch videos and contact the support team to ask questions about how to use this effectively. What problems are you solving with the product? What benefits have you realized? I have not had many problems because of how easy it is to use. I wish there were more payment options to choose from though.
